Hey is anyone out there casting for a 460 s&w ? I've been doing 230gr .45 and 158gr .38 with 3% tin 7% antimony is that hard enoughfor the 460 if used with a gas check? Not hunting as I live in Canada and not allowed. Target and some silhouette,thinking 300gr but it's all a guess right now. Shooting xtp magnums right now hoping to cast Look forward to any info Thanks Todd
