Although I’m an AR fan, and own one, I still use my 12 guage as my go to home defense gun. I’m not worried about over penetration, or under penetration. I keep my gun loaded in a very specific order. 2 heavy bird shot rounds to halt the intruder. 2 “000” buck shot rounds to put him/her on the ground. 1 hollow point sabot slug as a last resort. Perhaps you should look into this as an option. If you don’t own a shotgun, maybe look into frangible rounds for your weapon. They are pricey, but they are purpose driven, nor ahouls they be used as range ammo, self defense only.
