ggeilman, I second what superhornet told you. When seating lead bullets, you should put a very small bell on the case mouth. Easy does it. If you bell too much, the case won't fit into your seating die. Also,over sized bells that do fit into the die, can shorten case life by work hardening the brass, causing splitting at the case mouth. there are belling dies you can buy, but I get by using my size die. Just run the case into the sizer until the case mouth barely touches the expander ball on the depriming stem. Don't get too deep, and your lead bullets will slip right in.
