warningshot, your bouncing bullets off targets reminds me of what happened in the early 1970's when .223 Rem's and 5.56 NATO's were first used in competition. Folks handloaded their ammo with 52-gr. match bullets and didn't put much powder in the cases. When fired at 600 yard targets pasted on 1/2" thick hard cardboard backers, the slower ones stuck in the cardboard like tiny tacks. This was at a local club rifle range north a ways from San Diego, CA, as I remember.
