SWEET!! Looks like I'm gonna have to tighten it up some more if I'm gonna play with you guys

May be wrong, but think I know what $165 rifle you are dealing with from some previous posts/PM’s.

Thinking it’s a Chief. Never really told you the whole story about that.

One vid tester shot a 1” 100 yard group with a Chief when it first came out, which stated a mini-s-storm of posts here. In his case, random luck had everything come up “right”...the average rifle has a few “wrongs”.

They really are not “match” rifles. An occasional freakishly good group doesn’t change that.

Everything below on yours could be “right” as it came out of the box...NOT SAYING you have to do any of this, just that I liked to tinker.

My philosphy of groups may be different. With center-to-center measure, am thinking more about how to get the strays back into the heard rather than making the a good “core” (herd) smaller.

Had two, a .22 and a .177….turned out the .22 was the very first type, without an external spring adjuster and the .177 was the later type that did have an adjuster. Will be a NOTE 1 about that at the end of this long post.

A lot of playing around with each of them. Lot of testing and shooting in between, and that alone may have more to do with results than anything I actually did.

Typical QB type trigger. It takes awhile to break and in stay were you adjusted it, but a nice trigger pull.

Made sure the space between the gas tube and the barrel was even and that it ran down the middle of the tube looking top down with the barrel band off (trying for stress free). Was a little high spot on the bottom of one breech that needed to be stoned down to get to that...the other breech didn’t have that little defect.

Tried it without the barrel band and with the barrel band at various locations. Turned out (for me) it needed the barrel band, but location wasn’t all that critical. Be careful, the screws used on that band are absolutely “dinky” (one had little slotted screws, the other tiny tiny allen screws).

Did polish the rear end of the barrel slightly...not enlarging it, just to get rid of any tiny burrs around the barrel port that the pellets have to slide over when chambered.

Barrel crowns looked good. Re crowned anyway. Looked better, but didn’t change accuracy that I could detect.

Stock bedding doesn’t usually play that big a role in PCP’s. The Chief shows it’s QB heritage by using just one stock screw. If you loosen that one stock screw and the metal work wiggles around or tips up and down in the stock, are inducing random stress when the stock screw is tightened down. If it sits “even” in the stock, then just “two-finger” tighten the stock screw.

Swapped scopes with other airguns a lot...everything from short 4X to long 24X...expensive and cheap. Past a certain point, magnification didn’t help (that point seemed to be about 8X for 40-50 yards for me).

Even “top swapped” the two rifles (swapping the barreled breech) looking for any differences that might have made.

Normally test with 4 5-shot groups. Works out with the Chief, as something like 20-25 “good” (low velocity variation) shots is what you generally get. Normally only test shoot under the best conditions, want to test the rifle/pellet/shooter more than I want to test the effects of wind.

Will be an NOTE 2 at the end:

Always have started testing at short range (20-25 yards) to weed out the pellets that shoot poorly. Can always get 25 yard tests, but 40 yard test are more rare for me, weeding out the hopeless saves time/effort.

Winners in the .22 Chief were the 18.1gr. JSB’s and the 21gr. Baracudas….but that’s just one guy’s barrel.

----------------------

Anyway, the .177 was worth about .65-.75” at 40 yards (average of 4 5-shot groups in center-to-center measure). Not great, not bad, as far as I’d used a .177. In general, with 4 groups, would get a freak small one balanced by a big one...that’s pretty much the way of averages.

The .22 more like ..45-.60” at 40 yards….which is actually quite good when you don’t discount any of the 20 total shots and the human behind the trigger doesn’t screw up (one good screw up can really hose the results, but if you shot it...gotta count it).

NOTE 1 (as mentioned way up above):

Both of them eventually blew their valve stem poppet. Parts supply from Beeman is basically non-existent; had to make my own poppets. NOT something I want to do unless I have the valve/rifle in my hands.

Which is why I offer encouragement to owners...but try to steer new buyers to something that you can buy basic factory reseal parts for. That wold be o-rings and a poppet...of the two, can usually locally source o-rings.

So long as I was going “guts deep”, combined the two rifles. Swapped out what felt was the best of the two into one (.22), what I felt was the worst of the two into the other (.177) as a “spare”.

Now the spare has been cannibalized for more parts. I stripped the barrel band screws….adapted the .177 barrel to work on a QB78 co2 (it takes a bit)….took the scope for another rifle.

NOTE 2:

So my best, even though it’s not 4 x5shot with one pellet….it’s 2X 5 shot with two pellets….and I’ve not been able to duplicate it (one or two always seems to go “hermit” on me...runs sway to live all alone.)

Thanks ribbistone, I did not do any homework before I purchased the Beeman for 169 on amazon. In my day Beeman was quality. I had no idea about the parts issues. To bad because for me and my hunting style the accuracy is great and I also love the wood stock and feel of the gun. Oh well I am a tinker so when the popit goes with all your help and others hopefully I can make my own

. Hey everyone what are you thoughts on the Akela. I'm loving that fine piece in 22. I wish it was available in 25. Are parts readily available for it. Love the 5 year warranty.

Likely you will read this recent thread more carefully than I will. https://www.gatewaytoairguns.org/GTA/index.php?topic=196620.0

Dang I better start looking at other options. Thanks for the info on that one.

Ribbonstone · « **Reply #27 on:** February 25, 2022, 10:36:00 AM »

Found out (after two), am not a bull pup fan. Like me, if you think you might like them, may as well find out one way or the other. I suspect it’s mostly a style issue.

Nothing mechanically wrong, didn’t leak, just never found “full power, butt balanced, shorter” to be an advantage for any of the shooting I do.

Here another recent thread but in the opposite direction.

this isn't a group but I think the picture will explain itself..... note the Fly legs

and it's at 12 yards not 40

done with the Mrod with Crosman piranha .22

It was a super warm 60 degrees F today, so I did a little target shooting with my .177 Gauntlet Gen1. I bought her new 1.5 years ago - she has all her original o-rings except on the pellet probe. She holds air perfectly and shoots 10.3g JSBs at 865-67 fps. I have only added a two stage trigger and ditched the long shroud for a shorter shroud (ditched the baffles and spring too). Today was my second shoot since adding a 2mm thick carbon sleeve to the barrel. 10 shot groups at 41 yards were both .61” ctc. The 5 shot groups were awesome (by my standards) measuring .24”, .29” .34” and .25”. The last group of the day had my first 3 shots measuring .09” - this is a .177 at 41 yards! Of course my one flyer of the day happened on the next shot - but then took two more shots and they were dead on target. I took the shroud off and took a picture so that you can see what it looks like. I don’t see any reason to cover the entire barrel - as the flex harmonics are in the muzzle end - but maybe I will eventually. I love .177 btw - much easier to find great pellets than for my .22s - which are always backordered these days. This $200 .177 Gauntlet shoots right with my $1,000+ rifles at 40 yards.

GREAT SHOOTIN EVERYONE!!

55 yards 20 mph winds 5 shots 25 caliber 29.5 grain. 3/4 plywood didn’t stop the slugs.

Here’s a couple of mine. I’ll get my Origin out tomorrow & a 40yrd group with it also. One target shot with my Caiman X, the other is my Sentry.

Man these guns are real shooters!!!

kbstingwing · « **Reply #36 on:** March 11, 2022, 10:29:18 PM »

I don't have pictures of my HW100's targets, but they can put pellets through a keyhole at 40 yards no problem, very accurate guns....

Wow! That is a seriously great 10-shot group at 40 yards! What does your RAW shoot the JSB 18g at? Assuming that you sorted and weighed the pellets used in this 10 shot group…

No, this is straight out of the tin, hand loading. Generally speaking my pellet tunes will always be between 880 and 900. Last time I crony it was 892 fps.
Gun is custom tuned my Allan Zasadyn, easily the most accurate gun I’ve owned/shot.
Short, crisp shot cycle. With his mono shroud, it’s super quiet.
The barrel is an FX superior liner, permanently bonded into a 16mm steel tube.
