Hi people, I want to run a test for different bullets, both cast and popular hunting J-words in 30 caliber. Got into an argument with a guy at my gun club about bullets and bone hit fragmentation and thought I"d find out for myself. I intend to shoot through damp newsprint but would like to also simulate a shot that hits a thick bone. I though about using a piece of wood put in front of the newsprint. Any suggestion on what essence to use? or maybe plywood?
