[QUOTE="lyle2231, post: 2809457, member: 76736"] Asking for comments and opinions…I participate in NRA High Power matches. I use an AR with an 18” barrel with adjustable gas block .223 Wylde chamber for across the course. Prone matches are with a bolt gun in 6Br through a 26 inch barrel. I’ve documented my loads and my findings are that the 18” barrel has a shorter pressure curve duration evidenced by brass appearance compared to amount of powder in the case, at maximum or slightly exceeding. With the bolt gun I can’t get close to maximum before I start getting pressure signs on the brass. Two different set ups yes but the question is pressure curve versus barrel length. What are your thoughts…… [/QUOTE]
