[QUOTE="TheDerkster, post: 1195921, member: 92447"] I've been having issues with seating 195 eol in my 7mm Sherman short mag. At first, I had problems with every single bullet. What happened is the seater crushed the bullet and therefore slipped further down resulting in a longer base to ogive length called John whidden who makes the dies and he sent me a larger expander ball and different seater inserts after discussing that it was probably a neck tension issue. That alleviated much of the issue, but it's still inconsistent. It seems that I'm still getting about half of the bullets with a ring dented around the bullet from the seater. This causes it to seat 10-20 thousandths less than desired. I thought maybe it was due to powder crush, but it didn't help any using less powder to the point that I could hear it shake. The only thing I can think of to do is take a bullet and lap it to the seating insert so that they mate almost perfectly. I've never experienced this so I'm at a loss. I basically seat everything, measure, and then keep seating what's not right deeper until it's right. [/QUOTE]
