I like 223AI but it isn't for everyone. It gives me another 100+ FPS out of a 22" barrel, which really shows at distances beyond 600. Fireforming is easy, just shoot 223, and accuracy is pretty close to the real thing so you can play on steel. The biggest thing I like is that I don't have to keep trimmming the brass once formed like you do with 223.Just a question for the .223AI owners out there, is it worth the hassle of fireforming for the increased capacity and powder burn? Does it reach higher velocities and accuracy easier than a .223? I have a T3x varmint 223 and it’s amazing, was wondering about chambering the next barrel to .223AI.
