Ran across this stuff and it sounds pretty interesting: http://www.rbcd.net/Personal%20Defense-%20Ammo.htm What do you guys think of the idea? A fragmenting, lightweight (relative to the firearm being used) bullet fired at very high speeds to produce (claimed) energy of 828 ftlbs in .45acp. Has anybody seen or used this stuff? Would you use it for a carry load? HD load in an apartment building maybe? The Box o Truth did some tests with it: http://www.theboxotruth.com/docs/bot38.htm Their findings were that it was lacking in the penetration department, but I think that's sort of the idea with this ammo. Use a small, fast bullet that fragments to dump all the energy into the target. It would seem the stopping power could be impressive with these, but I think I might worry about under penetration if someone was wearing thick leather and several layers of clothing.
