    Seriously guys, .223. It's great fun on metal targets that are mutli-layered. Ever hit a coffee can with one? Friggen amazing! It goes in one side blistering fast at 3,000+ fps and makes a little hole less than .25 inches big, then blows back out the other side over a half an inch. I don't have any slo-mo video of it but I attribute it to the bullet tearing that metal it bit off at a high rate and pushing it out the back end along with the tumble of the bullet after it gets offset from that first impact to make a much larger hole in the back. I can't imagine what would happen if you actually tried pushing it through something nearly solid.
