Maybe I missed it but what twist is your barrel, the brand and length? I am surprised RL26 did not perform that well as others have really sung its praises. My 280ai with a brux 25 inch barrel just can't reach 3000 fps which is where I would like to be.
Brux four groove, 9 twist, 28". I'm at 136 rounds total as of today. I had it out again early this morning after a thorough cleaning (velocity was creeping up) and again, spot on. Velocity dropped back to normal still single digit ES. Sub half MOA at 300 yards dead center. Yesterday both groups were a hair under half MOA. I just can't seem to have a bad session with 4831SC. I'm going to stick with the 9-1/2 Rem primers.
