I use a Lee Precision reloader with the quick swapable dies. For the record, I do not like this press, I can never get the dies to stay put for some reason. When full length resizing I screw down the die down to the shell holder. Then tighten the die and start. For some reason it always loosens up and at some point I notice the shell holder is not contacting the die.

I think as I was FL resizing it loosened up. I just ordered a Hornady overall brass length measuring tool, I am going to measure some brand new brass I have and the resized brass to make sure I didn't bump the brass back to much.
