I was just wondering Doc makes a 45 Cal. sabot bullet for the 504 ultra mag. So what would happen if you shot a 480 Gr. .451 or 460 Gr. cast trash can in his long petal sabot? bullets are easy to come by and molds are to, like the volunteer and whit worth. Do you guy's think they would work for you. They could be sized .450, 451.or .452
