TSS: Tungsten Super SHot. True, it is for reloaders only and there are only a few places you can obtain it. Further,the folks actually doing the testing (thousands of their own dollars worth) and patterning keep their load data very close to the vestand WILL NOT give their recipes to just any Joe reloader. It is sold by the pound for around $50-$60 per pound depending on where you find it. It weighs 18 gm/cc, that's 80% denser than lead and roughly 50% denser than Hevi Shot and is very round. Starting out at the same velocities, it won't hold any more energy than the equivilant pb or hevi pellet. It will however penetrate better due to its smaller size and the fact that it is VERY HARD, and thus will break a neck bone with ease! It will pattern similar to any other HTL sjot but likes a slightly more open constriction.
