So Im about to take all my parts into the smith,(rem700, Kreiger 7.7 twist .224 barrel) to be made into a .223 rem Match shooting 75-80 gr Amax's, I have been bouncing all around at what length to cut the barrel, at first i thought i wanted to go with a 20 inch, but then I got all worried about loosing my velocity, so I thought 21 or 22, but now I'm going back to my original argument that I want short and stiff. I DONT KNOW! please convince me one way or the other.
