12 ga Shotgun for me, I prefer pump. Mine are all older Rem 870 Wingmasters.
Part of the reason I prefer shotgun is that with small shot there is a vastly decreased chance of a projectile going through both sides of a wall and killing a family member (Or uninvolved civilian) in the next room.
Lever guns are fine but a full power .30-30 round is not going to be stopped by 2 pieces of 5/8ths Sheet rock.
When you plan for in house defense you need to take into account who could be there.
You do not want to trigger a .30-30 round at a bad guy, miss, and end up killing your grand daughter a room over. You dont want to do that.
So the smart man eliminates that as a possibility. He takes the .30-30 out of play. Put it in the same room as your family would retreat to. Teach your wife, son, daughter, SOMEONE to use it effectively, and super carefull.
And all this is what I figured out, YMMV.
Ohh and once they are out and running, let em go. They are no longer a threat. Shoot them and you become the bad guy. So let them go.
Go love your family, they are scared.
