The A.I. versions look cool & different only to those that know ammo. They gained 100fps, which means little for hunting. No real gain until you need a bit more to stay supersonic for long range target shooting.
If you have good brass, case life is longer and case growth is slower. If you have to scratch an itch, the .223 is as good a place to start as any. Lee make inexpensive dies. date is easy to find. No change in Barrel life. Don't put your Remington brass hot loads in military brass.
