I'm digging my first one and waiting on the second. 50's at 3,700 and 75's at 3,150 is a lot of fun. I think Steve Timm pushes 40's out at 4,000. That is certainly nipping at 22-250 velocities with less powder, muzzle blast, recoil, barrel length and not to mention available brass. Fireform loads shoot just as tiny groups as the formed loads. If a guy likes the .223 he oughta love the .223AI. It's just funnerer.
