I have cast muzzle loader ball, conical, minie, modern pistol and revolver bullets and had good luck with them thanks to info from Lee and board members here. Now I want to produce a heavy 215 or 225 grain 8x57 load for the many Mausers I have (48, 48A, 98/22 & VZ24's). Need to know leading free fps I can expect with and without gas checks. I need advice on: alloy, which Lee mold is likely to work best...8mm Karabiner 215gr or 8mm Maximum 225gr, use of WC867 or WC872 with no duplexing preferred, std or mag primers, etc. I have lots of hard birdshot, soft lead, and can easily get wheel weight alloy to copy recipes. Please point me in the right direction for success. Thanks
