Ya, bought a synthetic Chief II in 177 for $179.00. Will shoot slugs 12.5gr to 15gr for long range stuff.
Plan on putting out about 22 fpe at 825fps with 15gr slugs ---- and with the high BC slugs, I get 18+fpe at 65 yards, and a drop of ~1 inch at 50 yards --- This should be a tightrope sighted in at 40 yards !!
I do think with the Chief II I can get that velocity without to much problem .... Ribbonstone will chime in for sure - ) ---- maybe Nervoustrigger also - )

Have no experience with the Chief II...and a little confusion.
Beeman is messing with me here.
Isn’t the wood stocked Chief II listed as a 2K fill (like the Chief)….but the Chief II synthetic stock listed as a 3K fill (like the Commander). If that’s true, then something more than a stock change is going on.
Can’t tell by the pictures what sized (diameter) the air tube really is….could be the “fat” tube used on the Chief…..could be the skinny air tube….ain’t gonna buy one just to find out.
Considering your previous posts, you may be OK….can make a part if needs be….’cause I’ve had no luck getting parts (check out the blown poppet posts and the Crosman mag conversion posts).
For a new guy, I’d wave you off….but likely you can deal with it if the time comes.
So more questions than advice:
Is it really a 3K fill rifle? (SHAME I to have to write that, but as an old guy remembering the “classic” Beeman, the current beeman deserves the lower case “b”).
Does it use a basic QB type valve (skinny tube like the co2 rifles) or the fat Chief valve (fatter tube)?
If it is a 3K rifle, then it likely would come out the box near what you expect (like 19-23foot pounds in .177)..or easily adjusted to be that with no mods. Out the box, the single shot Chief would at 2K (just not for a long string).
One way to look at it is 3K is 1/3rd MORE air than 2K....so if adjusted like the 2K Chief, should get more shots per fill at the same energy.

I checked all over and yes the Chief II is 3000 psi ... That is the reason I bought it for that extra poop to push a heavy 177cal slugs. If it was 2000 psi I would not have done it. My QB with 1000 psi output and shooting 12.5gr slugs is getting around 775 fps ... I do think the 825fps with 154gr slugs is possible with this gun.
Believe me I will write about it - )

Just seemed odd that the wood stocked Chief II is listed at 2K….plastic stock at 3K….but I’ve kind of grown use to odd things from Beeman in the last years.

Should be the 3K version (using the ad pics, can mag up and read the stamping on the front of the air tube).
Projected speed should be doable...a little adjusting, likely no mods….wouldn’t be surprised to see more than 825fps with that weight pellet.

Yes, I THINK so. Thought i would get the gun today but it will arrive on Thursday, Yes, I'm impatient as %$#*&.
Will be testing out slugs with this gun, both 12.5gr and the 15gr'rs. Nick "MAY" have some heavier 177 cal slugs coming out after he does his testing ;- )
Now the big question: Does anyone make a regulator for this gun ? Not a Lane, that I would need to drill a hole in my gun type ?

Sure is VERY, VERY funny that Chief II is 2000psi but the synthetic is 3000psi. I think the Synthetic although cheaper is an upgrade to the Chief II. I will gladly take that extra 1000psi. I could be very, very wrong but this could be a real sleeper - ) Wonder if the changed the Poppet also ?
Would love to get a second barrel band for extra security also, I'll check the man who shall not be named web site.

Hmmm, I see it is a repeater as well. Interesting.

Yes, it looks like a Chief II with a nice looking synthetic stock, but they upped the psi in the holding tank. They "MAY" have upped other things also, but who knows. The airgun market is so competitive at the different price points, the only way to stay ahead is on price and features. This gun may have done that for the ~$200.00 price point !

Supposition until proof.
Can figure out a few things as soon as you get it, without taking it apart.
Price wise, the $180 is a great price for a 3K repeater.
Hard to guess the diameters from an ad-picture, but if the outside diameter of the air tube is about 1.25”, suspect it will have Chief sized “guts”.
A regular QB tube is more like .865” outside diameter...which is also why all the “guts” (valve/striker/end caps) are different from QB’s.
So it is likely the 3K tube they used on the Commander….and likely the Chief ‘s “guts”.
IF that is right...it’s a Commander sized tube...then:
Does use the same QB78 trigger...which isn’t perfect, but is adjustable and can make for a good trigger by just twiddling the (tiny) provided screws. If you are a real trigger-ho, could shim the looseness out.
At least Beeman ( thought Pyramid air) does advertise spare mags….so likely Beeman has started to supply at least some basic parts. Honestly, aren’t impressive mags, but they do work..but you’d need at least two to make having a repeater really useful.
Once you k now the INSIDE diameter, can hunt up regs that might work (besides the Lane). Have some regulated rifles, mostly for long-long shot counts at lower power….unregulated for short shot counts at high power (logic being if I have to hit the "bejesus" out of something, I don't have to do it that often).
-
Hmmm, this may actually be a really Really new “in between” version - check this comparison review between the Chief II @2000psi fill and Beeman Commander @3000psi:
https://m.youtube.com/watch?v=qudP7givjTg
-
Watched it....thinking "bigger air tank" isn't correct....thinking 3K would be "bigger" than 2K wood stocked Chief II, but look the same physical size to me...so 136cc's at 3K is "bigger" than 136cc's at 2K so far the amount of air.

I am sure that all Chief II rifles are 2000 psi maximum fill, and the 3000 psi figure is an error. There are a couple of other errors in the advertising copy.
I would not order without guaranteed verification.

I think u may be incorrect, I have seen close up pics and the manometer reads to 3000 psi and there is a warning on the tube that says don't fill over 3000 psi --- but we will see tomorrow when I get mine --- stay tuned :-)

I do not mind being wrong. Only the truth matters. But I think we are both right and both wrong.
After some searching, it is not that the synthetic stock version is a 3000 psi model. In fact there are Chief II's and Chief II Plus models. I found a website (foreign language) with a wood stock Chief II Plus that clearly shows a 3000 psi fill level
So there are Chief models, Chief II models in wood and synthetic, and Chief II Plus models in wood and synthetic. Makes Commanders somewhat redundant.
So, for the short term, we have a number of variants in the hands of vendors. Order carefully. ;D

Craig, good post and good info -- it will be interesting to see what I get ;-) I'll keep you posted with pics when I get it later this afternoon. If this gun does have a 3000 psi tank, this could be a real sleeper gun -- We will see ?

-
Well, well, well it is a Chief II Plus --- That is the reason it has a 3000 psi tank ! and yes they never said that in the advertising, as you can see it says Chief II PLUS and the box says 3000psi.
I could not open the box at work but that is poor advertising on Pyramid Airs part in not saying it is a Plus. At that price it is a whale of a deal and it has the best features of a chief II and the Commander, minus the bigger tank.

Modern world Beeman....they really can't get their "snit" together.
Forgot to advertise it as a 'plus" model...which explains the 3 K fill over the regular Chief II and would have avoided all the second guessing.
Box mentions "..177 12 shots/ .22 10 shots" in one column and "single shot bolt action" on the other...I'm assuming that it comes with a single shot adapter.
Does visually look like a different magazine from the 1085 co2 repeaters...maybe even the Chief II....it's a visually different mag.
For $180..and a buyer that has at least some experience with PCP's...seems a price that would be hard to beat.
-
A data point (ad copy) on the box has a statement of (up to) "100 shots in .177", and similarly "80 shots in .22".
The implication is that the tune or set up is to maintain the velocities of the Chief and Chief II (non-plus), and add shot count instead.
That maintains a place for the Commander with its higher velocity.
-
We’re having a good time hitchhiking on another guy’s gun buy.
The BS of advertising...some are better about that than others, but what’s printed on the box is often exaggerated to the extreme.
It’s that “up to…” thing.
I’ve never had the patience to keep shooting, counting, and watching the final pellets of a fill dribble out the barrel at falling snowflake speeds..but it’s quite possible that it would do that ‘up to” 100 times before one got stuck in the barrel.
-
Finally got off work and set the Chief II Plus up, this gun is a monster, the barrel is ~ 15mm and the tank diameter is 31.75mm or 1.25" This gun is heavy and my trigger as it came from the factory was ABSOLUTELY HORRIBLE, it was a incredibly heavy and creepy 6 lbs. I will take the gun out of the stock after work tomorrow, and see if I can re-work the trigger. The butt section seems light, but the mid section is a brute. This gun may use the QB trigger but the rest of the gun is a brick house. This gun is more than a QB with a 3000 psi tank attached for sure. The gun came with two magazines and two shot trays, a nice feature ;- ) I use a single shot tray 95% of the time
Yes, it is a 3000psi tank, I started shooting at 2900psi. My first shot was 900 fps with JSB 13.43gr Monsters after I had tuned the hammer spring down one complete turn +. This gun when shooting slugs will be an absolute flat shooting tightrope --- eating every pest in its path !
Just about every shot I kept turning the spring power down, at 15 shots I had the velocity down to 845fps with the Monsters. I must have turned the hammer spring down by at least 5 turns.
With some serious testing I'm sure I can get a 20+ shot string of 800+ velocity shooting heavy pellets (15+gr) in this 177 cal gun - BTW: My Nielsen 15gr 177 cal slugs came in today. In reality if I had good tuning skills I would probably get 30+ shots.
I might add the moderator works OK, not the best in the world but it does keep the noise down. At this power, if it did not have a moderator, I'm sure my neighbors would be having fits !!
All in all I'm very happy with this gun, it is a monster and a powerhouse ---- ESPECIALLY at its price point. I'm looking forward to final trigger work and sighting in tomorrow for an outing on Saturday !
Sorry, I could not take pics, hopefully tomorrow.

Hey Will
Throw an SSG in it and do a fine tune, that should change things for the + side.............. ;)
That sounds like a QB on steroids' that grew some----- ;) LOL
Are the mags like anything else around? Mrod?
Thanks for the info.
Don

Congrats Wil! Sounds as though there is lots of adjustability.

Beginning indications are the Beeman Chief II PLUS is the new low end (by MSRP) champion.
That trigger assembly, originating with Crosman in the 1960's, has great potential. It's current wide implementation, QB's of all flavors (CO2 to the PLUS), and the Gauntlet express its usefulness. Too bad Crosman is not as wise with their low end rifles.

Yes, I agree, This gun and scope weighs in at 9.37lbs without a sling. The gun is built like a tank, I wish I had a Chief II to compare it to. I will have fun doing a bit more testing later today, I will see if I can get a shot curve but I don't know - That may take some time !
This gun is no joke, it is a well made gun especially for the price ----- I like it so much I bought another one, that one in 177 also !
Below is a pic of the ammo I plan on using. 12.5gr Nielsen slug on left, Nielsen 15gr slug in the center, and re-designed Monster on the right. The gun is way to powerful for anything lighter IMHO. The 15gr slug in the middle is the one I plan to use most of the time in this gun !

You say that the psi tube is 1.250" in diameter, that's about the same size as an Mrod?
How long is that psi tube?
I'll be waiting to see just how much room is inside that tube, in ref to the hammer/spring area etc,
for fitting an SSG............ ;)
Thanks,

Should be an airgun-sin to sell a repeater with just one mag (listening Gamo Urban?)….removes ½ the real use of a repeater. Single shot try is also a plus, esp. when adjusting/shoot/adjust/shoot.
At least they’re advertising spare mags (out of stock)….they are visually represented as the same for the Chief II and the Commander. (and reported to work with the co2 1085).
Assuming it’s the valve I expect to be in there….it’s a good design (except for old one’s poppet material) for power….larger diameter than the skinny QB valve, better factory air flow, valve port size for a .177….it should make power if that’s a goal. A bit of adjusting, no mods, could see +900 fps from those 15gr….would be a bit of a “Korean Cliff” type tune.

(that's the valve I expect in a Chief's 1.25" tube.)
You almost have me reaching for the buy-button….but there are too many PCP’s about the place already.
-
Sounds like a good candidate for an absolute firebreather of a .177.
A few months ago I set up a QB79 with a 1500psi bottle and it managed ~850fps with the 15gr Sniper Magnums (24fpe). Almost no plenum volume and much lower pressure compared to the new Chief. So with a little porting work, you can surely get those Nielsen slugs going faster than they have any business going.
Like Robert, I’m tempted but I’m going to hold off. Frankly I’m more curious about the journey than the destination. Even the QB I mentioned above proved to be more of an icepick than I had any need for so I backed it down a bit for happiness with stuff in the 9 – 11gr range.

Ribb
Thank you for that photo of your herd...............quite impressive arrangement,
nice to see them side by side and named etc.
I am just about in the same boat, as for the buy button, have the rat hole funds built back up........... ;)
I need want a good HD 177 cal for pushing the heavy weight ammo.
I have been looking at the Mrod, but something sticks in my craw, about that bolt hanging out the back etc.
This is the reason I have been following Will on his Chief II 177 saga etc.
Just maybe I can kill 2 birds with one stone, a 17 for indoor pesting (with the right tune),
and then the HD end...... balls to the wall (with the right tune) etc.
If I can get it to work with both fuels, so much the better, even if I have to wait till May/June for the Co2 ;)
Tia,

Don:
Confession of an old airgun-nut.
Probably bought 2-4 ariguns a year for about 17 years, and sold few of them. (yes, they made PCP’s way back in 2003)
That’s &^^& load of air guns. Really got back into pistol shooting just to save space...but that’s another clutter of airguns.
A few I gave away, very few I sold off, and some I just gave up on as “turds” and consigned to the parts box, some “tinker toys” I combined, some I boned picked for spare parts.
Even gave away a few as przes to forum members who guessed a quiz right.
Some of the mega-turds I pounded into the ground as tomato stakes...one I beat to death with a dull ax in a fit or rage.
Lets be kind and say there are 44 of them still around...so the pictured “cheap PCP “ is a significant percentage.
TOO MANY...either your passion/hobby is shooting….or your hobby is fixing….and they all need fixing/adjusting sooner or later.
With that many, there is always one or two non-turds that need fixing or adjusting….you’ve reached your personal limit when the choice is between spending a day fixing or spending a day shooting.
(ever watch Jay Leno’s garage….were I rich, I’d have someone else to rebuild/fix them and I’d just “drive” them)
Which is why I’m a fan of “simple” unregulated PCP.s ….they aren’t hard to diagnose and fix...so I can fulfill both time constraints (fixing and shooting).
------
If this doesn't make sense to you now...check back in in 2031...maybe it will by then.

Leave home from work early to do some testing, fill the gun to 2900psi and let her rip.
Monsters coming out at 885fps, turn two complete turns down, ( now that makes about 7 turns I think) now Monsters at 844fps --- that's OK cause velocity will only rise for this early test.
I put in a 15gr slug get 775fps and 12 more shots it climbs to 795fps and I stop. The 15gr slugs fit in very easily I might add into the bore. Manometer is at 2500psi, so I got about +-14 shots with this early test and as I mentioned an average of 785fps running from 2900psi to 2500PSI
I could have very easily bumped speed up another 75++fps but why bother ---- at this speed and with that 15gr slug I have over 16fpe at 65 yards and when sighted in at 40 yards I have about a total of 1/2 inch variation in height to about 45 yards and at 50 yards I'm an inch low :-) I can live with that, my initial energy is about 20.5 fpe ---- the slug does the rest.
I filled the gun after sighting in to get ready for tomorrow.
I will have this gun and my QB78s HPA, both in 177, both are sighted in with slugs, the QB with 12.5gr'rs not 15gr slugs.
I will have a pic of the gun tomorrow for sure along with the lowdown on the mornings shooting.
Nvreloader .. The main tube from the beginning to end is exactly 24" long ---- Hope this helps.
wll
-
Thanks for being the “beta tester”.
Good to have the length number…..with that diameter and length, likely listed as 136cc’s in volume, even more sure the valve itself is going to be as pictured in my last post….really won’t need any valve porting/mods for a .177.
(Yep...could have made a while new set of guts…..but am thinking they used what they already had and world work, exp. at that price point).
Transfer port/gasket would need a looking at….that’s usually (as you found with the 78S) the choke point. If it stalls at something like 20-22 foot pounds, I’d take a look.
Probably a longish thin solid bolt probe...long enough that you’ll have to lock the bolt back in it’s cock-on-opening slot in the receiver to get the mag in or out...and long enough that it’s fiddly to load the single shot adapter.
Will mention that VISUALLY..the mag looks different in the PA rifle pics than the ones shown in the accessories...but if you have two, have pretty well covered the reasons for a repeater (practically….if you missed 2 mags worth, a 3rd or 4th isn’t going to help).
Still thinking….Beeman really hasn’t got their “snit” together:

Hopefully, you’ve been out putting the PCP to some critter-use.
Just not my fate today….all I got it paper/swingers/and some old forgotten Halloween milk-duds to shoot.

Get out to my location it's approximately 6:30 in the morning I put on my FX Chrono, fire a couple shots at 2900 psi and getting about 775 fps first thing in this 45° morning.
I shoot a little bit, time is now 7:30am and have shot 10 shots, the velocity now has climbed to 785fps after the 10th shot, tank pressure is about 2450psi. I will shoot some more to get an idea when she hits the end of at least 775fps, so far at 10 shots I have not seen any major spikes :-)
The LDC works better than I first thought as my initial testing was from inside my house. All I hear is the mechanism moving upon shooting.
I took a couple of 42 yard lasered distance shots and that 15gr slug is there "NOW", I also took a couple of 43 yard shots and again, that slug was on target and there fast ____ The power is very deceptive as the noise is so low.
I'm noticing that I'm starting to shoot higher my tank is reading 2200 psi now, I'm wondering if my velocity is rising. I have 7 slugs left out of the 25 I pulled out to shoot. I turn the Chrono on again and speed is staying in the 775-785 area for the remainder shots and one more----- and then starts to dive.
Bottom line is as I have the gun set up I'm getting 26 shots, all in the ~775 to ~789 area -- starting out at 2900 psi and going to 2000psi shooting 15gr NIELSEN slugs. I can live with that, I don't know if it is good efficiency or not, but it's OK for the power level I want. I'm very happy getting 26 shots and a extreme spread of around 15fps, for me that is just excellent. I'm sure a SSG would be help me be more efficient and get more shots.
On this gun I have seen you can remove the big screw that tightens the mainspring and also remove the mainspring from the back end I do believe. I don't know if that would allow doing a SSG much easier or not --- I need Bob to chime in on that one :-)
Also because you are able to remove the big 12-13mm screw as I saw on YouTube on the Chief, a replacement screw could be made and an indexed knob could be attached to dial in spring tension to change velocity on the go or keep velocity up by tightening after 25 or so shots, possibly to get 40 + shots in your selected velocity zone :-) ? Pretty much like an Airforce Airgun or a Career :-) ---- I'm loving this idea , :-)
As always, anyone with thoughts or questions please ask or add input, we are all trying to advance and we all can help each other.

Thanks for the info, that psi tube is just 2" shorter and .260" smaller than the Sentry tube.
Kinda looks like I'll get one for the HD end in 177 cal and I do have a spare 20 bbl laying here.............. ;)
I hope it has MORE room than the Discovery, as I am really working real hard to fit my SSG into it,
less than 2" total overall room .......... ::), but I am getting there.............LOL.
By any chance do you have a diagram of the parts etc?
Sounds as if it has the power, just needs some minor tweaking...... ;) to get the most from her.

Got use to the “attention investment” of another guy’s PCP.;
Just a rough estimate form an outsider’s point of view.
That would be 136cc’s, running from 2900 to 2000, with 15gr. @ an average of 780fps for 26 shots.
Realizing it’s just a ball-park type of estimate….its a good start for using 900psi
For a non-regulated PCP, that’s a nice tight velocity limit ..although not being in a home shop/lab and measuring each shot, you might have missed something.
Something like 1.0-1.1 FPE/cuin on air use (using about 16psi per shot)..which isn’t great air use, but if it’s not your effort going into pumping it back up to 2900psi, many not matter.
COULD drop the mic now...say I’m done...and just go out and kill 25 critters per 900psi refill.
Suspect you won’t….will get the PCP fever of either more power….or more shot count...or both.

Out at my location, 6:20am, this time I'm stationed around the backside of the old barn, this is where most of the Feral Pigeons have been leaving for their morning outing and where the Starlings have been causing misery for every living thing they see. I'm approximately to averaging 55+ yds away which is in the strike zone of the Chief IIs + that I'm using today.
I have been coming here since about the first of the year about every weekend this past year. The pest birds have come to recognize my car and once they see it, they are gone --- so today I'm doing a dipsy doodle and I'll try to fake 'em out a bit.
Chief is set at 2900psi for its opening shot, 15gr slug is loaded up, and I'm in waiting :-)
Just lasered and I'm actually ~ 53 yards away, with a possible 63+ yard shot on the long side where I am.
A Feral Pigeon pops up, cock gun and let 'er rip ---- first shot after resting all night was at 763fps at 63 yards and the shot was low, windage was perfect. My scope is set at 10x. C#@P ! I shot a few more test shots and adjusted the scopes elevation. I should be good now, gun is now pumping the slugs out at 775 range giving me ~16.5fpe at 55 yards. AGAIN, The gun is so quiet in 177 all I hear is the mechanism and I can hear the secondary bounces letting out air that is wasted!!!
I can say this gun could be a world beater if it had a SSG or maybe the "O" Ring thing (I forget what it is called or how I can do it on this gun , - ALL HELP IS WELCOME :-)
It must be spring as the bunnies are starting to come out, If I'm out walking around I usually talk to them and tell them to hide from people like me, (in case you are wondering, I really don't shoot rabbits, except Jacks).
The sun is up and it is in my scope, I MUST make a lens shade for this gun !.
Have fired off a few more shots in practice and air is around 2900psi, no more Feral s have popped up and the Starlings are off in the boonies :-)
It is now 8:50am and the sun is starting to heat things up. I will wait a bit longer and I may bring out my Red Talon CO2 Gun.
It's now 9:20am and there are two Ravens 76 yards away playing kissy poo , it's definitely spring time :-) I Have fired off a few more shots, all velocities are in the 775+ range, very consistent, I have shot 16 shots and the gauge is reading about 2800 psi ---that is crazy good, maybe it's because it is warmer, I don't know, but the tank feels cool ? Maybe it's SSG'ing itself Lol, Lol, Lol.
I'm heading home after a fun day, this gun is surprising me in a lot of good ways for sure.
Got a question, I won't be shooting this gun till next week I think, should I let about 1/2 the air out to save the poppet valve or will it matter ?
Till next time, stay safe -

I've seen a couple of hunting videos where the shooters have captured live Starlings from before, and placed them in cages to bait in the other Starlings with their distress calls. Treacherous but highly effective!
-
Went again, but only stayed about 1/2 hr, it was hot as heck !!!
Did fire off 5 more and velocities were in the 778-785fps range, tank is down to ~2700 psi, that is with 21 shots.
Man alive I'm impressed, the fact that I'm not getting a major spike in the velocity curve impresses me greatly ;-)
wll
-
Finally got off work and set the Chief II Plus up, this gun is a monster, the barrel is ~ 15mm and the tank diameter is
Yes, it is a 3000psi tank, I started shooting at 2900psi. My first shot was 900 fps with JSB 13.43gr Monsters after I had tuned the hammer spring down one complete turn +. This gun when shooting slugs will be an absolute flat shooting tightrope --- eating every pest in its path !
Just about every shot I kept turning the spring power down, at 15 shots I had the velocity down to 845fps with the Monsters. I must have turned the hammer spring down by at least 5 turns.
With some serious testing I'm sure I can get a 20+ shot string of 800+ velocity shooting heavy pellets (15+gr) in this 177 cal gun - BTW: My Nielsen 15gr 177 cal slugs came in today. In reality if I had good tuning skills I would probably get 30+ shots.
I might add the moderator works OK, not the best in the world but it does keep the noise down. At this power, if it did not have a moderator, I'm sure my neighbors would be having fits !!
All in all I'm very happy with this gun, it is a monster and a powerhouse ---- ESPECIALLY at its price point. I'm looking forward to final trigger work and sighting in tomorrow for an outing on Saturday !
Sorry, I could not take pics, hopefully tomorrow.

I decided to JUMP over the edge (won't be the first time) I'm GOING to set up an onboard externally regulated auxiliary tank on my Chief II + (say that 3 times fast).
I have some small tanks at home that I will regulate at an outgoing 2500 psi. My Chief II + tank will start out at 2950ish psi and when it gets to 2500 psi I will turn the open valve on the auxiliary tank that starts out at ~3000 psi and let it regulate the Chief tank at 2500 psi as long as it can - from previous testing I start to lose velocity at 2000psi, and that is where I stop. This gun as it shoots now keeps its velocity very well at the pressure setting of 2950 to 2000 psi (from ~775 fps to ~805 fps at this pressure range on a very gradual power curve).
The auxiliary tank will be strapped to the gun the same way my QB78s is set up --- The man difference beside outgoing pressure is it will be a hose connection, giving the system a cleaner look and allowing the auxiliary tank to be set back and balance the gun better ---- A 3 inch Velcro strap secured to the gun will be the holding mechanism.
Being a 13ci auxiliary tank is about 213 cc's and the guns tank is from what I gather 135cc, that gives me another 63% more air volume and about 27ish more shots :-)
We will see how this plan comes to fruition ?
The main reason for this is when I shoot heavier slugs (17-20gr's) I will need a bit more air to send slugs at my 775 + velocity --- yet I still want a very good shot count !
We will see what happens. My Griffin 17gr 177 cal pills arrive on Saturday !

Does seem like it would work at 3K if you didn't turn the tank on until the rifle tube shot down to under reg. output.. Worked with a tether line and a large tank.

So, are you saying that the air tube is the same O.D. as the Chief?

I thought the original measurement (same as M-Rod) was in error, but not having a PLUS in hand, declined to comment.
The Commander may have the M-Rod tube diameter (or close).

Yes, the tube diameter is ~1.023 --- I don't know what the Chief tube diameter is as I only have the ChIef II +
I wonder if the Chief and Chief II + tubes are the same ... would be interesting to really find out the difference ? I have absolutly no idea if the attachment method is super strengthened or not on the II +, all I know I would never put more pressure in the gun than manufactures recomendation, that is suicide !

Same diameter. Your length estimate is off for just the metal tube (no end caps), likely more like 23 3/8ths.
We're just never sure if the metal it's made from is the same, the value of unrated retention screws, or some other small design change internally. Keep it to the listed pressure and you should be OK.
Were some vids/discussion....lot of Chief's post at one time.

I’ve not run the .177 Chief over 2K, even with the new retention screws...for me, the 2K fill was one of the reasons I bought the rifle.

Got the Griffin slugs today --- here is a pic the 12.5 Nielsen on the left, the 15gr Nielsen in the middle and the 17gr Griffin on the right. I will take the Griffin out on Sat, chrono as I sight in on rocks and see how they do .... Hope they perform well and It doesn't take much power adjustment to get them in the 775 fps zone ?
Will be shooting the Chief II + as you would expect.

2K works for me also. I was just wondering about the safety factor on the Chief II. I have seen a lot of poor designs in my life.

Best guess tune for the 2K single shot .177 “Chief” version….but it took awhile to get there and it’s not greatly efficient.

Being unregulated “hunting guns” (rather than bench guns) generally just count all the shots that stay inside of 4%….could likely use 5% 6% if the range is short, I just got use to using 4%..
And the best guess the for the .22 version of the 2K Chief….which is slow for a .22
(https://live.staticflickr.com/65535/50316606601_0ea16e8320_z.jpg) (https://flic.kr/p/2jEiL92)DSCN2924 (https://flic.kr/p/2jEiL92) by Robert Dean (https://www.flickr.com/photos/144930793@N07/), on Flickr
Could go a whole lot faster (even at 2K)….but a whole lot fewer shots….or a whole lot slower, but not a proportional increase in energy….just where the issue 2K Chief ended up.
Am thinking, a Chief II plus...as an unregulated 136cc PCP, with a 3K fill…assuming the same “guts” …..would very likely balance out with HIGHER energy, but likely about the same shot count
UNFORTUNATELY.,...through wear and tear, some ill advised mods, and the lack of factory spare parts….it’s now ONE functioning Chief.
Turned cannibal and scavenged one to keep others running…..but do have a full Chief “upper” (barrel/breech/mags) and that will “top swap” with the lower (stock/air tube/valve/etc.).
But am now thinking I should “steal” the 5mm co2 conversion QB “upper” and give that a try on the 2K PCP lower...and/or steal the 3K PCP QB .25 upper and give that a try on the Chief’s 2K lower.
It’s not mods….just “top swapping”.

Excited about going out tomorrow with the 17gr .177 cal Griffin slugs in hand. I hope 17gr slugs stabilize in this gun as I'm getting close to pulling the trigger on a Corbin swaging airgun kit.
The adjustment power wheel is marked to I can get back to zero, I hope the 17gr slugs get up to speed without over a full twist on the wheel. I know I will lose shot count, it will be interesting to see how many ?
I estimated another 10% in BC with the extra weight compared to the 15gr slugs I was using ... so that gives me now about a ~.082 BC. Muzzle at ~775 fps (22.7fpe) and ~ 691 fps (18fpe) at 75 yards --- Great !
Gun is pumped up to 2950 psi, I'm excited. Hope the Starlings are out;- )

Went this am C II + in hand and started to test the Griffin 17gr 177 cal slugs, cup base, started at 3000 psi and ran down to 2000psi where it started to nose dive.
Turned up Power Wheel 180° (one half turn), velocity started in at 742 fps and rose to a high of 776, for a total of 35 shots and an average of 757 ---- I can live with that ------ what I CAN'T live with is the horrible accuracy of this 17gr slug in this barrel. The slugs fly true and straight at my 43 long yard setting although accuracy was way sub par, sighting in at 26 yards at my painted sight in plate gave ~2 1/2+ inch groups --- at 45.5 lasered yards I would miss a 4" steel pole and when hit the group would be ~ +5", I have never encountered anything THIS bad before. All shots were shooting straight and I did not see any wobbling of the slugs in flight with my 12x scope. All shots were using a sandbag rest on my car window !!
Opening 26 yard test shots below, first ones fired at center hole, (high shot was very first shot with this ammo at 6:30 this am) --- right target 2 shot group after windage adjustment.
(https://photos.imageevent.com/wlleven/k10dtest/downloadphotos/17gr%20Slug%20target%2026%20Yards%20sm.png)
These slugs are undersized for my bore as they go in without the slightest resistance, they measured on a CALIPER (My micrometer battery was dead) .177 - My NSA slugs measure .178 ---- and I think that is the difference. I may try to flatten the bases on some for testing tomorrow. The NSA slugs were very accurate BTW ;- )
I do like the fact that these slugs arrive at my intended targets right now and with serious oomph ! I do love that !
For best velocity consistency so far with this gun 2850 psi to around 2100 psi, giving around 25 high velocity and ~ consistent shots. I can live with that, although at the distance that I normally shoot (40 yards and under), a few fps variance means little and I would rather have the higher shot count.
The 15gr NSA slugs gave more shots but power wheel was turned down, can't get something for nothing !
---------
3 hrs Later !
Just got my micrometer, NSA = .17785, GRIFFIN = .17734
I think that could be the reason accuracy is not up to par !

Can I ask what kind of mic that you have that reads in 5 decimal places, i.e. 1/100 of .001 inch? I can understand one half a thousandth. What I am trying to say is that you can only read out accurately to 4 decimal places. Any more than that is PFM and not to bother with.

The heavier slugs will need to get up to the speed the lighter ones were shooting good at to be of any worth IMO From my experiences alos ;) 8)
I was out pesting with my DAR .177 and 12.5 NSAs dropped a possum at 50 yards , and no it was not just playing :)
I think the dar is in the higher 20 fpe range IIR , need to do more trials with some cronys, q Lab Radar is on my bucket list.
Keep playing you will get there or take what it will give you!

Set up the C II + with another 1/4 turn up for more power,(Back_Roads suggestion) first shot was 763 fps as was the last shot of a 27 shot string --- high was 789 at the 16th shot. I can live with this shot count at the velocities using this heavy 17gr slug in 177 cal. This set up is giving me 18fpe at 75 yards !!!
The changed velocity and air strike on the slug may have helped a bit with accuracy as the gun "Seemed" to be shooting a bit better, not great but "Doable" ---- 32 yard group was ~3\4", thanks Back_Roads.
Soon as I can find a ~ 17-18 gr slug that will shoot in this gun well I'll be in pig heaven ! I do think the issue is the slug needs to be .1778+, .1773 does not cut it. .178 or .1782 would probably be perfect !!
I got to say I love this gun, the good shot count using heavy 177 cal slugs with their high BC giving me great trajectory and down range energy makes this a long range pest gun for sure --- 18 fpe at 75 yards is more than awesome for my use.
I have seen YouTube videos where they talk about the gun being loud, Well in 177 and at the velocity I'm shooting with the main spring turned back at around 4 + complete turns the gun is quiet, not Donny FL quiet, but quiet.
I might add at this price point of $179.99 IMHO this gun is just awesome, the 3000psi tank, the adjustable hammer spring to tune to your liking, getting a good shot count or more power or whatever you want --- an adjustable trigger and a LDC --- lots of features for a great price !
So much my musings on this Easter Sunday -- Everyone stay well , till next time.

Good to see positive results, nothing like a .177 ice pick to a pest thinking process. Now where did that rabbit go ???

I have Griffin 17gr hollow cavity slugs arriving on Friday, along with some Seneca 16.1gr dome pellets. So far she shoots the NSA 15gr slugs just great and the JSB Monsters are terrific also. I'm hoping the 17gr Griffin hollow base shoot better than their 17gr cup base do in my gun. From all reports the Seneca domes shoot very well in PCP guns so I'm excited to see how they do in the C II +

Spring time….have done the .177 power-PCP in the past , but no factory ready swaged slugs at the time. +30 foot pounds wasn’t hard to set up with a couple of PCP rifles...but the pellets of that time resented being pushed that hard.
Come early Fall….if God permits….will set up the same .177 test rifle (Bam 51) with a selection of slugs and see what will happen with “modern” .177slugs.

I just contacted Steve (AVS Slugs) to see if he had any 177 slugs coming out, and that I wanted ~.1785 OD .177 are not cutting it, .1778 are pretty good, but still can stand for some improvement !

Set my gun up at 2700psi and cranked my power wheel 3/4 of a turn up from my 15gr NSA Slug starting point.
For 10 shots I averaged 801fps and 18 yard accuracy was ~ 1/2+ inch. If I was steadier I could have done better.
Also shot my new Griffin 17gr Hollow Base slugs and they shot like #*>×₩€<(. I think a few were starting to go in sideways.
I checked the rifling on the slugs and it was visible but not grabbing the slug, don't have this issue with the 15gr NSA's I have been shooting. I will be powder-coating the Giffen slugs to see if the added diameter helps.
Griffin slugs are very nicely made and are very consistant, but this gun may have a bigger bore and that's the issue !!!
Much more testing to come !
PS : Does anyone know the BC of the Seneca ( Eunjin) Domes ?
wll
-
EunJins can work...doubt the BC is all that high, but I’ve not tested it. Need two working chronographs to shoot over.
Are a bit slower than I expected….likely because of bore friction (a lot more of the pellet actually touches rifling).
Different rifle...but the same idea of a fast .177.
These had been pushed though the bore to see check the fit...EunJins were “fat heads” but shot OK.

Turns out, nothing LONGER than the JSB’s would shoot...the two on the right showed tipping and never made it to a longer range test. Turns out, for that rifle, anything over .31” in length wasn’t stable.

Various ones dropped out by 50 yards…..moved the 3 winners to 75 yards.

Sure looks like the 13.4’s made more of a rip than a clean hole at that range….stability is a bit suspect.
No idea what your barrel will like or hate….or how fast you want to try to push them. Bumping the above from “soft tune” to “hard tune” kicked speed/energy up to about 30foot pounds...but the only result was that the lite pellets shot worse/shot count shorter.

Would have been fishing if I didn't get lost and had to go back home, but that is another very, very disappointing story.
So I'm out to test out Seneca 16.1gr domes this am, instead of wetting a line ---- I have my power set 1/2 turn up from my NSA 15gr slug setting.
Hoping that starting at 3000 hope I get 775 fps so it climbs to ~800+ish and back down after 25 + shots.
I will make power adjustments after the second shot if things are not right. Let the show begin :-)
Well I took two shots after I adjusted the wheel 1/2 turn, 800+ fps, to much in the beginning so I un-turned it a quarter of a turn--- velocity in the 782fps mark, I left it alone. After 10 shots she is shooting 798fps at 2800 psi, and I know she will start to climb.
At my test target steel plate it is apparent this gun loves the Eunjin 16.1gr pellets, easy ~1/2" accuracy at 26 yards. At 43 yards my elevation is good (a touch high) as much as I can tell.
I checked and checked for a BC on this pellet, and the best I could find was from years ago a guy shooting 1000fps and got a BC of .035. Well since I'm shooting ~200 fps slower and BC decreases with an increase in speed near/at the speed of sound (I believe) I gave this pellet a BC of .037. I think I should be close but BC is often different in gun to gun, atmospheric conditions and bla, bla, bla.
Anyway, saw rabbits and song birds so far, nothing I would go after, so I start to shoot at some small rocks and twigs at a lasered 54-56 yards away (depending on what side of the hill I shot at) and I smacked everything in sight, I have NEVER shot like that before at those (to me) very long airgun ranges. I might add it hits with authority too !! I have shot 19 shots and the gauge reads 2400psi+
I shot to 31 shots total today and the gauge read 2000 psi and my last shot was 789fps, so I stopped. My average velocity was 802fps, with a low shot of 779fps, and a high of 820fps. Most shots were in the 800fps zone for sure. My average muzzle energy was 23fpe !
I was absolutely amazed today at the accuracy of these Seneca (Eunjin) heavy domed pellets. Honestly, without exaggeration I was hitting targets the size of medium size walnuts at 54-56 yards, something I have never done at that range -- and it was smacking those targets with authority !!!! ----- What a sensational Starling, Pigeon, Jack Rabbit, Ground Squirrel gun this is !! At around the 55 yard zone I get about 15.5 fpe, more than enough for all those critters !
Going home to put this gun away ---- again I'm very impressed with this gun, I may have just gotten a good one, or just tuned it right through the guidance of experience from the guys on this forum - I'm happy.
Here is the efficiency of this gun today !

You’ve got a nice hunting PCP...for cheap. Plastic stock won’t get AFU….enough shots for an outing...shoots slugs….good energy/trajectory for a .177….simple enough to keep running for years (with a nod to the poppet discussion)...repeater/ 3K rifle.
Your NEXT PCP (and there will be one as you are firmly hooked now) would likely increase one factor over another….different caliber...more power...more volume...more shot count.....prettier…whatever.
This one is getting “it” done….the next one would be to get a different “it” done, even though it might be a less often needed “it”.

Thank you for all the info and test results,
I have been following along and have not found this info about that C II barrel, so far.
Do you know what the twist rate is for the OEM barrel? It seems to shoot the heavier weight VERY WELL.
As soon as I get my Dar holding air, I'll check the twist rate of the OEM bbl, and hope it is close to the C II twist rate.
I among others here, would be tickled Pink,
if NOE could bring out a 177 cal mold designed along the spec's of the best HW pellets,
like you are shooting, and a 4 base pin selection would be icing on the cake etc............. ;)
Thank you,
Don

I wish I new what the twist was, it shoots 13.43 gr Monsters very well as we'll as the Eunjin 16.1gr pellets.. 12.5 gr slugs are very good and 15gr NSA are OK. The gun has an issue with slugs that are .176.7 to 177.3 in diameter as the Griffins I have are..
I have powder coating material coming to increase the diameter about. 001, and I hope that does it :-)
Of course if the twist is to slow then I'm at a disadvantage with heavier slugs.
I was very happy that the accuracy was good with the Eunjin 16.1gr domes.
Yes,, if you can find the twist rate that would be great..
I have calls into Beeman about the Poppet and I'll call tomorrow and ask what the twist rate is, hopefully they will get on the line..
Thank you again for your response.

The only reason I still have my 1085 is because of superb knowledge and patience of Ribbonstone for QB78s in general. Thanks to his teaching, I've got it shooting really well - much more consistency and hitting harder. Last week I checked it - 6 shots from 571 to 573fps with 10.9gr at the far end of a 14 yard test (ie, NOT muzzle velocity).
And I plan on working on it more to improve performance. A few weeks ago I put a reflex sight on it and got that dialed in. So I'm really happy with it - no thanks at all to Beeman for service after the sale.

I did achieve the desired result (that was three years ago); 22 good shots --- 783 fps - 802 fps - 781 fps --- from 1700 psi to 1250 psi. A few more shots were available, but my requirement was under 20 fps ES. Oh, .22 caliber - 14.3 grain CPHP.

Was out early and tested some NSA 15gr 177 cal slugs. I turned my power 1/2 turn up from my 16.1 gr Seneca Domes. My velocity with the slugs is 810fps and giving me 17fpe at 75 yards. My manometer is going down faster and I think I will get around 25 shots at this power setting, going from 3000 to 2000psi. I have shot 18 shots and at 2400psi on the manometer now.
I tested the accuracy and at 25 yards all shots were in a dime for sure, my 45 yard shots at inanimate objects were spot on, there is one English Sparrow that was 43 yards away that is now tweeting in heaven along with a flying rat at a lasered 35 yards that was hammered and went down like a sack of potatos. I have shot 25shots so far and I'm at 2200psi on the quage, so I'm guessing ~27 shots at this power setting.
Nope ---- at 2100psi velocity starts to drop, so +-26 shots is it at this power setting and an average velocity of 810fps, 21.8fpe at the muzzle, and 17fpe at 75 yards ----- the high BC slug REALLY makes a difference downrange ! Almost 1/4 more fpe than my 16.1 gr Dome pellets at the same range, not to mention the much flatter trajectory. The high BC of the slug gives the same energy at 75 yards as the Dome does at about 53 yards.
------------------------------
I get my sizing dies in about a week from now and will size my powdercoated NSA slugs to see if that might increase velocity a bit. I have two dies, one at 4.52mm and one at 4.53mm
As it stands now ----- Seneca 16.1gr Domes and NSA slugs are the ONLY ammo I will shoot in this gun. The Domes are really accurate and hit like a ton of bricks (they do not need sizing), the NSA slugs extend that same 17fpe energy out about another 25 yards or so !! Ya got to love it :-)

Any idea how that pickle is attached to the barrel?

Shot mine a bunch today. The gun was nothing to pump to 3k. It actually has a nice consistent shot string below that anyway. Probably no need to fill past 2900 or 2800. It wouldn’t shoot 7.9 gr xman hp premier. They were terrible. Really liked H&N barracuda match 10.65 at 900 ish FPS. Didnt really group test them yet but with them I was able to bang the little plates on the xman squirrel 🐿 target at 41 yards just about every time. They were 100 x better than the xman pellets. Gun didn’t seem the least bit loud to me either. Worth 180 bucks so far.

Any idea how that pickle is attached to the barrel?
I believe the LDC is press fit with two sides of the barrel flattened, so it can't twisted off ---- IMHO a horrible design, very stupid, but If they become popular I'm sure Donny FL will make an adapter for them:-)

Might be the right adapter here ? If not that vendor may have that also.

Different barrel for the Chief (which comes bare-barreled) and the Chief II (which has an LDC attached).
Think William is right about how they are attached….maybe even a press fit with adheasive.
Those 1/2-20 adaptors are useful if you already have a screw on LDC you want to use or planning on buying a screw on version. I
Either the adapter grub screws on, then you add the screw on LDC….or just go with an LDC that grub screws directly.
-
I figured it out. It's actually a threaded barrel. The LDC is "notched" so that it can't spin and then there are 2 nuts holding it on. Kinda odd but it looks like they are M12x1. Thought it might be like the Skyhawk at M12x1.25 but nope. It's M12 but finer then 1.25 so must be 1.
You have to spin off the end cap with a 8mm Hex wrench. Then the baffles and spring will come out. Then I made a tool from an old 9/16" socket to fit down inside and grab the 2 flats of the retain nut. (They are round with a flat on either side.
I have an old LDC with delrin that is threaded 1/2-20 and the barrel threads will "re-thread" the LDC and it looks to be plenty secure. Should be much quieter since the original only has a little over 3" of air space.

Sure thing. Also the crown (if you call it that) is recessed down the barrel about 1/4". Great for protecting it, if it were nice. It was horrible. I had to use a ball cutter to open up it up and the re-crown it. Also just like some of the QB78's and 79's the bore is off-center in the barrel. Hopefully that wont cause any issues.
-
Thanks for the pictures...can see how it works/fits much better than just a description (more of a visual learner).
If it’s threaded, than can avoid the adaptor “middle man” and just mount the LDC directly (without the lock nuts) assuming the thread is common.
Issue version is short (but it’s “free”); likely would work for a low-power (less ejected air) tune….nothing wrong with being even quieter and adding a longer/bigger/quieter LDC.
Not one to condemn an off center bore on an air gun without testing…..usually find them after a shortening, but if they shoot well, I just live with it.

(OK...nearly flat crown….but there is an LDC that keeps it covered/away from damage...LDC pretty much acts as a real deep deep recess.

I'm at home staying out of the wind and I'm Johnsing, so I set up a target outside at 18 yards and shoot some Monsters Redesigned.
My setting is at my "0" O'clock starting point (0 is actually my starting point 12 O'clock position). 6 O'clock point (turning clickwise) is my Senica 16.1gr Dome setting, turning 180 deg clockwise 12 O'clock setting is my 15gr NSA slug setting.
I'm shooting these at 860fps, gun was starting at ~ 2300psi for 8 shots to around 2100psi
Shoots these at 18yds to my Seneca Dome point of aim although hammer spring setting is lower.
If I shot 10ish gr pellets and turned my power another 1/2 turn down or more, who knows how many shots I could get !!
This Chief II + is one of my favorite guns, mine in 177 gives me enough poop to pop pest the size up to large jacks to the 50yrd + range.

After shooting my Liberty so much my Chief II + got very jealous and she told me on no uncertain terms that she wanted to go out this weekend ;- ) So. I just sized about 50 Redesigned Monsters to 4.53mm and will blast rocks and stuff this Saturday (been wanting to see if sized makes any difference in speed). I will resize some Seneca 16.1gr pells also and chrono all.

Yes, truer words were never spoken ------ Just last night she was yelling that she did not want to shoot any pellets that weigh less then 10grs, that she was to powerful for those !! I told her I agreed ;- )
So I just sized some Seneca 16.1gr Domes to be sure they were 4.53mm This gun shoots these pellets incredibly well at a velocity of around 805++ and a energy of over 15fpe at 60 yards --- that to me is off the charts. I can smack small walnut size targets at 45 yards no problem and pretty much do the same at 50 yards using those pellets. I get (as I remember) about 27 shots from 2900psi to 2000psi.
wll
-
The Chief II plus and I are out at 6 o'clock in the morning, there's a slight wind it's pretty cold at 47° this am.
I'm shooting rocks on top of the old house roof at around 35 yards that are the size of walnuts and busting them shot after shot. I'm shooting 16.1 grain Seneca pellets at an average of over 810fps
They are screaming out of there and they are hitting hard - I have my hammer spring adjuster at about 4:30 o'clock, all is right with the world.
This gun is shooting lights out as always, have started shooting at a PSI tank pressure of ~2950psi+ approximately and hope to run pressure down to around 2100 before the bell curve really drops, I figure it will be about 26 to 28 shots. I can always turn the hammer spring up to get another bell curve going but I haven't done that yet :-)
Well she gets a good 25 shots and then she needs more psi to keep these heavy 177 cal pellets going. If I had the hammer spring turned down and was shooting some lighter Monsters my shot count would be higher.
I will shoot Monsters tomorrow, again must say every time I take this gun out I come away very happy :- )
I'm also very happy that I got this gun in 177 as I can turn the hammer spring way down get well over 60 shots and get over 800fps all day long with 10.6gr Kodiaks and even with this pellet smack small game for sure, or I can load up Monsters for more downrange smack or shoot 16.1gr Seneca Domes for serious hard hitting penetration. If my shots are longer I can use NSA 15gr slugs and easily get 17fpe+ at 75 yards.
This gun has loads of power and in 177 cal and outdoors the gun IMHO does not make a lot of noise.
Till tomorrow,

:o greatest little air rifle for the money. $179, 2 mags, 3k fill, just need a good scope and wish the pickle on the end was replaceable, leastways easier to replace. There is one guy on youtube that shows him taking his off and working on it. However, it's in Spanish and I don't speak Spanish and I don't fully understand some of the things he is doing. So I don't want to mess up my gun.

I'm out at about 6:30 in the morning with my Chief II Plus, hammer spring is set my "0" point and shooting Monster 13.43gr pellets - they are going out at 833fps at the start. The spring and hammer are bouncing around because there's so little pressure on them. I have the guns hammer spring set very lightly, this gun as I have said before --- its an extremely powerful for what it is.
My velocity will climb to the 860 area as it has done in the past and then at the end of the bell curve be in the 830 fps area again. (I pretty know the curve for this gun with Monsters, a full tank and my "0" home setting).
The PITA wind is blowing pretty good on this 52° morning, and my shots are to the right about 3 inches. At this starting velocity I get ~ 16fpe at 35 yards and 15fpe at 45 ---- I think that is enough for Starlings and Feral Pigeons :-)
Shooting Monsters in this gun is a very good general choice when slugs or the heavy Seneca Domes are not needed. I can tell at my 35 yard zone the Seneca hits harder and has more energy but at the cost of shot count, as that pellet requires about a 6 O'clock spring tension setting on my gun. There is barely any hammer spring tension at the start today as my "O" setting is so light only a little air is coming out and wasted seconday hamer bounch air burp is kept to a minimum or not relevant.
I backed off the hammer spring another 1/2 turn from my "0" starting point and have almost no resistance on the spring when I start to cock it. The amount of pressure is just enough to have the spring in contact with the hammer, MAYBE a micro touch more. With this setting I still got 821fps with Monsters --- that is fantastic - If I was shooting 10.6gr Kodiaks that is EXACTLY what I would do :-)
I went back to my original setting for Monsters and she is getting 846fps right now.
Well, after about 45 minutes more of sending pellets through the air, I'm through shooting for the day -- I got 39 shots from 828fps to 863fps, my starting psi solidly was on 3000psi mark and shot to exactly 2100psi.
I'm sure if I turned down my spring that 1/2 turn as I did just to test today and shot that from the start, I can get 45 shots averaging in the 825fps + area, as it was today my average was 848fps and that was with 5 shots in the peak zone that did not register on the chrony.
Kodiaks !!!
I have not shot Kodiaks from this gun, but as mentioned, if turned down 1/2 or maybe more to start out in the 800 - 810fps to climb to the 840ish area, I bet you will get ~50 shots and enough energy for pesting in the 35-45 yard zone for Starling, Pigeons, and head shot Squirels at the 35 yard mark!! At 810fps about 10fpe at 40 yards
You Ratus Ratus guys could have a field day supplying the coyotes for miles around with food :-)
Man, I love this gun :-)

A backwards research.
The spare mag ads claims the mag will fit into a QB II (1085) co2, Chief II, or a Commander.
(Warning #1: some times the published ads lie...have no way of knowing, but it's happened in the past.)
Beeman 10-Shot Auto-Indexing Magazine, .22 Cal. | Pyramyd Air
What I have on hand s the .177 CO2 1085, but according to the above, the mag should fit and work..)
It will fit and feed the Senica 16.1 gr. 177’s. Need a little poke to get those fat-headed pellets to get all the way down.
Cycles reliable, just a bit stiffer due to the larger pellet diameter…..don’t shoot well in the test rifle I have at hand, but the magazine worked and they COULD shoot well in your rifle. Co2 is really soft-balling those pellets, might be better luck to hard-ball them faster.
(Warning #2: "Same" pellet has chngged a bit over the years. Excluding the old .177 EunJin or Sam Yang versions, the Seneca versions at hand run about .305” in length. That mag seems to be able to function with lengths up to .34”).

After shooting my CII+ yesterday I decided that this up coming weekend I will use some 10.5gr pellets (Kodiaks or CPM's).
I will set the hammer spring about 3/4 of a turn counter clockwise from my zero position. Betting that the difference in pellet weight I still will be able to send these "Light" pellets out in the low 800's with that super low spring tension. At the counter clockwise 6 o"clock position I was sending out 13.43gr pells out at the 825fps ---- with less spring tension I may be able even to send the 10.5gr ammo out close to this speed :- )
If I am, I bet I can get well over 50 shots with a bell curve in the 815ish to 840ish back down to 815ish. With this tune I'm after Starling sniper speed and number of shots. I may even give the power wheel one complete turn counter clockwise if speed is to much. I really don't want to go over 830ish at the bell curve peak !!
We will see what happens this weekend coming up ;- )

Does anyone use a hand pump for this gun , was wondering how many pumps from 2000 up to 3000 ?
wll
My pump has a slight leak and I would say 50 maybe 55-60 with mine.
Do you know the size of the tiny o ring in the one way valve in the fill port?
