Well, I learn something new every day! Thanks for the info guys, I've only ever used 7 1/2BR in SR primers, and the only cartridges they've gone into for me are .454 Casull, .357 Max, and 6PPC. Obviously haven't had any problems, but I've never tried switching out to 6 1/2s either, and now I never will! Thanks!
