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.

Thank you, was read with interest. Thank you for the spring info.

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 :-)

Till next time,

Any idea how that pickle is attached to the barrel?

[Trucker3573]

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.

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:-)

[Back_Roads]

 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.

[RichH]

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.

Do you have pics  I would love to see how it's done :-)

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.

[Ribbonstone]

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.

Coerced gun rotation!
 

[Ribbonstone]

they get sulky if you don't take them out now and again....in human terms, you gotta take the uncoordinated son out for some pitch and catch, even if he isn't a baseball star.

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.

[wll2506]

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,

  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.

Yes, I have seen the video and I'm  with you.

I'll wait for Donny FL to make a good looking adapter and then us Chief II Plus shooters have our wish :-)
