[QUOTE="Buffalobob, post: 80931, member: 8"] Here is a long article on momentum and shooting metal plates. [url="http://horusvision.com/hv.cfm?pg=exitem&exp=davis_art-39.html"]http://horusvision.com/hv.cfm?pg=exitem&exp=davis_art-39.html[/url] With a metal plate you can get "back splatter" which will cause the momentum transfer ratio to be greater then one (semi-elastic collision). On soft animal tissue you do not get "back splatter" (totally inelastic collision). Having thought for only a short while on the bullet spin issue, my preliminary thoughts are that the fragments are flung out radially by the spin and cannot have a "spin induced" contribution along the path of the bullet. Their effect is 90 degrees to the path of the bullet and they open up the wound channel width not lenght (moving inertial frame on bullet center of mass). In other words they do not contribute to the target moving backward only exploding. Fast twist barrels explode dogs better than slow twist? Thats a funny thought.
