After playing with my new favorite toy (Quickload).....I'm seeing that AR-comp keeps coming up with good fill %, great velocities, near complete barrel burn, moderate max pressures, and most importantly muzzle pressures right in line with the favorite powders currently used to drive the Garand/ M1A's actions (about 4,500-6,500psi). Now, if I could just FIND some! Lol Has anyone else been playing with AR-comp? BruceB??
