In CA they consider a handgun caliber anything that CAN be fired from a handgun. Obviously that's open to interpretation by each retailer. I know Wal-Mart "asks" when you buy .22LR if it's for a handgun or file... will they require more questions and checking or will ALL ammo that can be shot from a factory sold handgun be considered handgun ammo even if it is not normal (30-06,.223, etc) and 99% of time used in a rifle.

Who knows?!?!
