For concealed carry it also a wise to use ammo that's has the neccessary "stopping" power without creating a situation where the families lawyer attempts to attack the the credibility of the reason you're carrying in the first place. In other words, if you use ammo that say for instance, is designed to enter and cause massive injuries with little or no chance of recovery and without due regard to the safety of others, they have tried to convince the grand juries that you carry just for the sake of killiing with little to no regard to the human life you took. Just something to keep in mind. Now for house protection, there's usually little to no regard in this since you were awaken by someone standing over your bed. Never - ever use ammo that too old.
