Sorry, missed going on yesterday. One thing with lead is that it is identifiable to a batch lot. I Presume Chummie is trying to say that he was shot but not by the murder victim. Lead shot or lead .22 bullets are made from scrap lead and as such will contain various impurities in varying proportions. Each batch will be as different as fingerprints. Yes, quite a quantity will be smelted at the same time and there will be several tons of identical shot or identical bullets but they will match to the individual batch. One load of Winchester lead .22 ammo in one batch will be nothing like another batch coming out of the factory a short time later. If the bullet in the suspect matches the remaining bullets (if any have survived the fire) then there will be a good chance that they will have come from the same batch. Circumstantial evidence again but the more the better. Interesting stuff lead and in fact a drop of engine oil from the sump left at the scene is identifiable to a suspects car as good as DNA and tyre rubber can batch match and also contain certain trace elements that match to a vehicle. All very scientific but avenues of exploration. Lagopus.....
