I’m disappointed you’re all having a conversation on ammunition and caliber types and what’s best for “home defense” but not one person has brought up Dr. Roberts
extensive research and write up on the matter that was posted on AR15.com
While I’m sure everyone’s
opinions cast some relevance, I’d highly recommend you familiarize yourselves with actual scientific knowledge and information before lighting off a few rounds in defense of your home. Theoretically of course, considering the nation in which we reside.

One point I did want to add, in regards to noise that someone made here. Unless your intention is to engage would be invaders and dispose of the “theoretical” bodies that are now strewn across your property, noise is your friend. I believe it was John Lovell (aka Warrior Poet) that said he wants his primary home defense gun to be a “fire breathing dragon” because noise attracts attention and attention attracts police. Let’s be real for a moment, unless we’re fantasizing about end of times, the police are exactly the people you want to be there should you ever have to resort to deadly force to defend your home....theoretically of course.
