Yeah, I have two 223AIs. One is an AR-15 with a 26" 1-14" twist barrel. It is a prairie dog machine with 50gr Sierra Blitz Kings, but unfortunately I moved away from that area, so I do not shoot dogs much right now. The other is a Hall bolt gun with a 22" 1-8" twist barrel. It loves the 75 AMAX, and I have about 700 bullets to go through before I need to find a replacement. (Maybe try the Nosler RDF next) It is very accurate and a ball to shoot with no recoil. Reticle stays on target very well. I really like the 223AI and it does everything I ask it to do.
