I like CB shorts AI. I also have an oddball rifle that is .40 caliber but uses the .38-55 case. Muzzle loading breech cartridge gun. Reverse AI. None of that is as odd as the OP's quest in my mind, such as it is. 7.62x39 AI might, just might, catch up to the .30-30, but I doubt it.

God knows how many 7.62x39s been shot at me, none of them have connected yet.

I am..........disturbed.
