That's whay I use these... No better ammo IMHO.
Mag Safe Ammo - Pre-Fragmented Saftey Ammunition Handcrafted In The USA
.223 rounds for home protection is just plain dumb in urban areas.. that round is soo fast it's a danger to everybody past what you're shooting at... even if you hit them.
Shotguns(not slugs), handguns (with that ammo), or my Good 'ol .22LR is all I'll use indoors for protection.
OH.. that and my two Pit bulls...hehe. I don't think I'll ever have to worry about using my gun with them in the house
