So here's the general idea of what I'm going for, but with a scope setup:
I have a Thompson Center Pro-Hunter with a 223 26" heavy barrel w/ a 1:12 twist. I just ordered the side-folding stock for it. My goal is to shorten the barrel to save a little more weight and make it more compact. The reason being: I've found an excellent caribou spot this year in the walk-in only area and used the .223 to take the caribou.
I fear changing the barrel in any way because I've gotten 0.3" groups at 50 yards with PMC ammo. I'm hoping the accuracy will be preserved and many people say that seems to be the case. My Ruger scout rifle sure is accurate with a short barrel.
Looking for opinions on barrel length that will function well with the 55 grain or 62 grain loads (thinking about the Federal XM855). At what length will I actually start losing velocity from the listed velocity on the box? Does anyone know what barrel length Federal chrono's their loads on? Even a 22" barrel would be a nice weight reduction and have an edge over most AR's out there. Has anyone chronographed PMC 55 grain or Federal 62 grain out of a bolt action (22 or 24 in)?
Also, what type of crown would work best for a 22-24" barrel in 223? Is there any significant choice to be made?
