How long should my barrel be for PRS Matches? I’ve heard guys run all the way up to 29” with a brake. I’m currently in the process of building my rifle. I’ve been going back in forth on 6CM and 6CM. After reading many posts on here and others, it seems like the 6mm’s are what’s trending and dominating the matches. I have a Bench Mark, 29” 1.8 twist 6mm barrel and I’m wondering should I have the gunsmith cut it down, or should I just keep it at 29”
