Has anyone tried a NOE 461-540 .461" 540 gr in a trapdoor with smokless powder? I'm tring to find a trapdoor friendly diameter bullet without have to pay the custom mold price. This is as close as Iv'e been able to get to the original government style projectile. The lyman 457125 is way too small a diameter for a proper fit and will not engauge enough rifling to stabilize.
Thanks
