I bought a Lee Collet Die for neck sizing .243 cartridges in a Hornady Lock and Load AP press. The problem I'm having is that the die is bottomed out and I get just adequate neck sizing. I've tried taking the lock nut off and that gives plenty of adjustment but of course the die isn't secure. Has anyone else run into this issue? Is there a fix other than milling down the lock nut or adding thread to the die? I don't have any machine tools. It looks like the bushing for the turret adds height to the die but there isn't enough thread to overcome the difference.
