After owning about ever cartridge and caliber you can think of I've finally narrowed it down to two(or three depending on how you look at it). 38spl/357Mag for Revolvers and 45acp for semis. Those are the ones I'm sticking with, if a handgun isn't chambered in one of those I'll not even bother looking at it. Figure after 51 years I should narrow it down to a couple that I can depend on and trust. So, has anyone else narrowed there cartridge choice down to a couple three as I've done or are ya' still open to anything.
