Just a thought,,, like Trailrider said,,, resize them all,,, that should bring them all down to .427 ,, trim them ,,, then expand to whatever size bullet you're using. Went through the same thing with 32-20 a few years ago. I had about 40 yrs. worth of brass that I'd saved up. 5-6 different headstamps ,, 5-6 different case lengths , only about 500 cases. Starline was the shortest, trimmed them all to it. In like Flynn !
