Yup, i agree. I notice that even the 225 or 275gr powerbelt in .45cal can handle more powder than the 50cals in HEAVIER weight! .45 has a much smaller HP and the nose is pointed more. I cant wait to try this insert out this season. I have to find aluminum so i can do a .45cal mold. I also am going to experiment with hardening the tip and see how that does.
