Hi. Ive been tying to make my p94 9mm shoot lead. I'm using ww air cooled 4 grains bullseye slugged my barrel at .355 sizing bullets to .357 using 2500+ lube. belling with lyman m die. I used the lee factory crimp die. I set it so it just removes the flair. I'm thinking that could be the problem. I don't get the min over all length. I'm using the lee 124 gr TC if I have it set to min over all length it would expose the lube groove. Am I missing something. this gun leads up pretty bad after a dozen rounds. I have done real well with all my other caibers but this one is not liking what I'm doing. Help Please.
