I'm using the Lee Breech Lock press. I don't mean to write like a smart a$$ but I understand how to adjust the die. It seems like over-night the edges of the collet have become sharp like a knife. The indention the die leaves is knife like. I may be able to post a pic, I don't know if it will show or not. I've already ordered a new die but would like to figure out what happened to this one.
