Hi there. We have a 12 gauge "pump style" shotgun that holds 6 shots. It is our primary self defense/home defense (after our dog, motion-activated security lights and deadbolts of course!) My question is, for home defense purposes what type of ammo should we keep the gun loaded with? I have purchased target load to practice with, but I doubt if that would have much stopping power for a bad guy. I was thinking about having the first shot be target load, and then the remaining 5 shots buckshot? The purpose of the first shot being target load is if I have to fire a warning shot or if for some godawful reason the gun accidentally went off, then there would hopefully be less damage. Also, at what range is target shot lethal? and how about buckshot? Thanks so much!
