22 Nosler take two

I’ve had no brass issues with mine. My rifle has a rifle +2 gas system on an 22” barrel and using a Vltor A5H2 buffer with the Geissele 42 spring. 55gr NBTs and 53gr Varmageddons are death rays on groundhogs. Always wanted to try some 40s but never did.
 
I have several 8's and a 12.
33 cfe223 and 55 Nosler bts at 2.280 with CCI 450's both shoot 5 shots well under an inch at 100 out of the 12 twist woa as well as the Wilson combat 8 twist. If I recall the Liberty 8 twist shoots it well too. The 8 twist bhw is a bit finicky but shoot very well with 53 VMAX and I think 33.2 grains of cfe223. I know of 2 other woa 12 twist and a predator contour 20" 8 twist woa that also is very accurate with the same 33 cfe 55 bt load.

Any of you 22 Nosler AR shooters have any updates on these things and how they're performing for you and what all if anything you had to do to make them run smooth in a suppressed AR build.

I'm looking at a all steel, not a CF wrapped, Proof Research 8tw 20in +2 barrel chambered in 22 Nosler barrel that I'll put on either a Seekins SP15 or Rock River AR15 with intentions to shoot either 53 Vmax or 55 Nosler BT's. Also have a bunch of Nosler 50gr LF BT's as well but those would likely be a third choice.
 
I have a 24 inch White Oak and it's been great. I shoot 52 gr. ELDM's and accuracy is sub MOA. I dropped a coyote with it 2 weeks ago, hadn't used it for 2 years. My suppressor is waiting for approval so I can't say about that.
 
I’m still running my 22” Wilson combat barrel, bleed off gas, H2 buffer, suppressed and I get very little if no case damage. I’m sending 55 grain hand loads right at 3500. Factory 62 grain Nosler loads are going 3250 and 53 varmageddon factory loads are 3450, and all shoot well. When I first put this upper together I was getting some case rim and head damage, sitched over to bleed off mode in the gas and put in heavier buffer and it really helped.
 
I had one of the first 22 Noslers with the cheapo stoner barrel, and it actually shot pretty well. With an adjustable gas block, I would have had no issues with torn up case rims, except for running suppressed. I've noticed on pretty much everything running suppressed ars, that if you tune it for the first shot through the can, that subsequent shots are over gassed and tear up brass to some degree. This can be mitigated somewhat with powder selection. A flow thru can should take care of it entirely. I'm not sure but I'm guessing the issue is residual gasses in the suppressor on follow up shots?

I was a big proponent of the 22 N though, I wish it would have taken off like a rocket, or even a Hornady product lol. I'm probably going to try the 22 Arc at some point, I think if you can get those high bc 62 grainers to shoot well it's the best of both worlds with good speed and retained speed downrange. The flip side to me though is if they don't shoot acceptably, and a lot of rifles seem to not like them so far, then the 22 arc is just another heavy bullet lobber. My buddy has found that the 69 tmk is the next best option and shoot way better in his.

Also been kicking around the idea of turning one of the same two I mention above into a 204 Ruger AR15 build. Based on your screen name you have some time with one. Have any thoughts you'd like to share about a 204 AR build?

I have some time with a few 204's. The first one would have been in about 2008 or 9, I had a local machinist turn a shilen blank into a 26" truck axle barrel that shot 32 nbt's into tiny groups. It accounted for untold numbers of prairie dogs, I never took it coyote hunting. I retired it a number of years ago now. My current one is a 22" ER shaw barrel from midway that I've had a year or two now, it shoots well and is a p-dog machine also. I load those with n133 at 4k fps.

What I'd say is use stainless mags and load to 2.3", sometimes that helps with accuracy. My wish is that they would have made 1-11 the standard twist rate, as 1-12 can be pretty iffy with the 40 grainers, and those do a lot better in the wind.

I also have a couple of cheap bolt guns, a RAP and a TC compass. The Compass is the better set up, the mags are better and accommodate a much longer oal and it's 1-10 and shoots 40's amazing. The RAP is getting long in the tooth, but they really messed up on the mags imo and it's 1-12. As well as they shoot, I much prefer an AR for p-dogging.

That was my thought on the 22 arc as well. It has a bit more case capacity than the 6 arc if I recall. Like you stated if it would drive tacks with the 62 it would definitely be worth owning. However if it doesnt then your back to heavies.
