There are a lot of strong opinions out there when it comes to home defense firearms. Nick’s Self Defense Tip; Don’t Use a Rifle caused some of the best discussion I’ve seen on the subject in a while, and it got me thinking on the subject as well. It seems to me that the biggest hang-up for any person, no matter what their view point is, is the issue of penetration. If I shoot someone in my house and miss, how many walls is it going to go through? Will it hit my neighbor’s house or go into the adjacent apartment? Is a rifle or shotgun round going to penetrate more walls than my pistol? These are valid concerns and ones that any responsible gun owner should consider. So I decided to get some supplies and see what would happen if I shot at and missed an intruder with the firearms I have in my household.
