 The 9mm, every 9mm round we tested went through all three walls and exited through the T111 siding we put on there. It would exit your home. We never, ever got an AR-15 to go through the third wall, ever. Okay, yeah, I have a Winchester, I believe, X. It's a 170 grain bullet. Not an AR-15, you don't. No, my 9mm. Okay.
