 The 9-millimeter, every 9-millimeter 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 9-millimeter.
