Well, it's not entirely what you're comfortable with either. You're not gonna use any .50 BMG weapon on an intruder. Or an 8-6 gauge shotgun. You also don't wanna use armor piercing ammunition in most weapons, or explosive ammunition. Or a machine gun... those are more for plinking, experiments, and generally harmless fun in a civilian context. I'd say you have to take into account both variables.
