In the 30 luger brass, I strive for .003-.005in. of interference fit so as to get as much neck tension as possible. You will still get a few thousands of setback, but that is of no concern. If setback is excessive, that is concerning. I have started to add a cannalure to my jacketed bullets, and then the collet crimp into the cannalure to give myself the best protection for setback. My 30 luger rounds are loaded near/at max loadings, and I can not afford setbacks.



Apparently Sieger types faster that I do!!

rhuff ,
The Lee dies I have came with a .307/8 expander plug , and the cast bullets I have are .312/3 . I have loaded a few more dummy rounds , with no crimp , and my set back is much improved ( operator malfunction ) . Probably in for a new set of dies that I`m more familiar with . By the way , that outfit in Montana ( Western Bullet Co. ),he has apparently lost his molds for the 90grn 30cal. cast bullets , and isn`t in a big hurray to replace it because he has not gotten back with me concerning a possible order , but that doesn`t diminish my appreciation for your recommendation , Thanks again , Don
