Thanks SeanSean! I continue to be amazed at the efficiency of the rubber crumbs and their stopping power. I have had another couple of chl classes with another 2K rounds or so and it just keeps stopping everything thrown at it! For those that have comments, if you have never used the rubber crumbs to stop bullets from penetrating a back stop, don't talk ugly about it because you sure as shooting don't know what the heck you are talking about. From someone that is currently using it and monitoring it each time shots are fired into them!
