[QUOTE="timotheius, post: 1865454, member: 66591"] I tried trimming the brass, and that did not solve the problem. As to the other questions: it is not a shoulder bump issue. I use a sinclair bump gauge and measure carefully to make sure I am getting the correct amount of shoulder bump. I have used both a redding FL bushing die, and a Lee FL sizing die. I used the redding die to fine tune the shoulder bump. I used the Lee die, contacting the shell holder with cam over, to try giving it a lot of shoulder bump. Neither made a difference. The black marker trick sounds like a good idea, I will try that next. [/QUOTE]
