pierced 3/16--1/4" steel tank side, (never measure it, ok?, 35 years ago). from 100m, and put BIG,extended "bumps" in the far side of the tank. the SX softpoint will not exit the body of a chuck. it's so thin jacketed. line up 3 full soda cans, hit it with this load, and the 3rd can will only be DENTED. What happens in fluids,(including tissues)and what happens in metal, wood, etc, are NOT one and the same thing, at really high velocities, man.
