Just wondering how hard you you guys are pushing your coated boolits in 500 Mag. I've cast some 440gn Lee's w/o gas check but they do have a heavy coating on the base. These are cast from range scrap with some extra tin added and cold quenched after coming out of the oven. So far I've got some loaded with starting loads of Longshot and wondering how they'd do at higher (near max) pressures and velocities. I've fired max loads with the same range lead/coating in 10mm and some start loads of H110 in 44 Mag with no ill effects but then again those weren't 50,000PSI loads. These will be fired from a 8-3/8" S&W. Powders I have are, AA9, 1680, H110 and CFE-BLK.
