 So that round would go straight to the dude that broke into my house, the wall of my neighbor's house. I would think 9mm would be better. All right, let me ask you this. What makes you think an AR-15 round is going to go farther than a 9mm round? Well, around here, unless you're buying expensive hunting rounds, everything is full metal jacket. Okay, again, you're making an assumption. What makes you think a full metal jacket AR-15 round is going to go farther than a 9mm round?
