[QUOTE="zr600, post: 1540903, member: 104269"] Personally in my experience a guy doesn’t get his gun as clean as he thinks it is. I recently bought the Lyman borescope and could defiantly tell my guns weren’t as clean as I thought. I use jb bore paste for the high carbon calipers or a heavily carboned barrel. You are burning quit a bit of powder. I would contact Barnes for load data they should be able to get you something close. Even if they just have 243 loaddata and not 243ai just start on the mid to higher end. My cousin has a 22-243ai I have a 22-243 he’s using Lapua brass and I’m using Winchester brass and I’m pushing just as .5-1 grain more powder then he is with about the same pressure roughly actually he has a little more he was getting ejector marks and I’m not. His brass should have more case capacity but it’s not showing that now. I’m shooting about the same FPS as him also and he has 2.5” longer barrel then me. To say all guns aren’t the same is understatement. [/QUOTE]
