Wanted to add 1-important finding that I found out later- ALWAYS, ALWAYS CHECK CHAMBER WITH GO/no go Guage!
My PrecisionAero HP bolt was out of spec and caused excessive head space! I will NEVER EVER EVER SHOOT A RIFLE AGAIN THAT IS NEW OR BUILD W/o checking this first!
Could that cause all the information below to be now voided? On a later date I will try again with a proper bolt!!!

wanted to give some information to save a lot of headaches for someone out there trying to use a Creedmoor 22 caliber and a AR 10 frame for use on small critters when using common bullets you’re in a 55 grn and 88 grn
Weights and give you my experience to help you know what to expect:
24 inch rainier barrel and had trouble reaching the high speeds the bolt guns reached.
With 4350 and other similar speed powders it would not get the speeds up for the lightweight bullets.
In fact at times I felt a 556 would’ve been just as fast.
With 41.5 grn 4150 and 55grain pill (tried many) = 3100fps
I played around with this for a long time and didn’t know what to do...
Should have posted on here...
Varget was the ticket= 40grn 3600fps+
This was 1st time I tried it.
41 gr too hot and did not help much with speed only 100fps.
I will continue to load it down just to see where the FPS goes is this the first time I tried it was just a couple days ago.
Varget may not work with 88ELD.
40grn Sw precision (varget copy).
ELD 88... Do not use way too hot Blew primer out and destroyed case.
I didn’t really have anywhere to start I don’t think I’ll ever try and do something like that again.
Posted some of the screenshots from the chronograph info but I hope this gives someone some help.
As far as anything to help with making the dwel timeincrease maybe +3 or+4 which they don’t make otherwise just use a heavy buffer tube, carbine length and a spring red from Springco A heavy duty spring carbine length.
I have tried everything else and it didn’t help not sure why manufactures would not try a longer tube for at least these overbore cartridges in the AR10 that may help!
All of the things don’t really matter.. or do anything to increasing speeds, or lessen cases damage while trying to increase dwell time ect.including the VTOL system.
It surprised me because I have a AR15 in the 17 Remington caliber and I did not run into any other issues that I ran into with a 22 CM in the AR10 chassis.
Hope that helps if anybody decides to take this on I’m probably gonna put it the barrel up for sale after my next hunt because I wanna be trying some different things.
