I own an 870 Express Magnum Youth Model 20 gauge, it is a very good self-defense gun because it is so small that you can swing it around in the house and easily handle it and pump it quickly. I have #8's in it, because it can't go through walls like buckshot will and up close it is gonna damage someone very badly. I'm just wondering if this is a wise choice to use #8's for home defense, will it stop an intruder? I know it won't hurt them as bad as buckshot will, but is it wise to use #8's or should I use #6's instead or what? Give me your opinion.
