I have been using those Hornady Lock and Load quick change collets in my lee press fo a while now, and I had a question. I notice that they move in the bushing a little tiny bit, and I was wondering if this could lead to an inconsistency in my final product. I havent noticed any problems yet, I was just wondering if anyone else had any problems with them. I like that they make caliber changes fast, and switching from resizing to seating is a snap, but I worry that they're not precise enough. any thoughts?
