[Spats McGee]

kraigwy, I am going to see if I can get hold of some of those texts, to learn more about the science side of it. You say that "most smokeless powders give almost identical residue." But do they leave identical powders at different distances? Will the residue on a human from a distance of 2 feet be the same as the residue from the same shot at 15 feet? 20 feet? If not, then distance can become an issue. If the BG survives, he will undoubtedly tell the police that he was just wandering home from choir practice, minding his own business, when he was shot for no apparent reason . . .
