I was at the range today, and saw for the first time ever the size of hole that a shotgun slug leaves in a sheet of paper. Most impressive. I've got an 870 full of 00 buck, but I might have to put a couple of slugs in the bottom of the magazine.

I wouldn't bother with the slugs, overpenetration issues, you might end up shooting a neigbor or family member, if you have any that is. I load the first 4 #4 then 2 OO. At inside the house ranges shot acts much like a slug anyways since it doesn't have time to expand, but it slows down when it starts hitting walls where a 1 oz slug will just blast through.
