Home Forums Hunting & Shooting Hunting Rifles What does 223AI mean?

I go for long on that frame myself. Had a 3 screw RSB for around 25 years, was chitt hot with that one if I do say so myself. Was the gun I started reloading with. Now that I think about it, was about 15 years after buying the RSB that I picked up my first CF rifle. Didn't see the need for Florida hunting. Not sure I do even now, but I grew bored with hand cannons.
