The AI case is a standard 06 case fired in an AI chamber to be formed with a 40' shoulder and less taper on the body, giving approximately 10% more case volume. Do you handload? If not then you'll need to start because there are no factory loads available for the 06 AI.

As far as whether or not your gun will shoot 06 ammo accurately only your gun will be able to make that decision. If you bought this and intend to only run 06 ammo through it I'd have to say you wasted your money, now if you handload then that's a different story.
