I loaded up 8 dummy rounds to check magazine function , which was fair , with one jam do to set back , which occurred on all rounds to one degree or another , so I have crimped them using a Lee Factory Crimp die . This appears to put a good hold on the bullet , but sets them back also . Like Mr.rhuff said ,"a work in progress". Thanks Don

Crimping on a non-cannalured bullet will not stop setback of the bullet, neck tension is what does that. In fact, if you overcrimp the case mouth, you can make things worse. What is the diameter of your case neck expander? What is the measured diameter of your bullet? 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!!
