Here's a test of the CorBon 9mm PowRBall in 100 grain, using 4 layers of denim over wet newspaper jugs. A big "thank you" to GT's KingLamoni for providing the ammo; he gets a shout-out during the video. I show the fragments at the end of video, including the polymer ball. Also, notice during the shot that I had a fragment fly off upon impact and into the lower left corner of my backstop. It is very evident during the slow-motion segment at the 2:46 mark. I went through the backstop (catalogs and paper), but did not find anything. There is a clean 9mm-sized hole in the box/backstop, so I don't know WTH it was, as I thought I accounted for all the pieces. Finally, check out the link in the video description itself, as you can view a ballistic gel video of this cartridge at the CorBon YouTube channel.
