Thread: Lee Collet Die Decapping Pin Removed

I've never taken mine apart - can you remove the decapping pin without removing the whole mandrel? The die is supposed to size against the mandrel, removing it would probably result in oversizing the case, and possibly wreck your die.

I have some dies where the pin removes from the mandrel. And others which are one piece.

The decapping pin is an integral part of the mandrel - the OP is considering permanently removing it by grinding so it doesn't push out the primer. You definitely need the mandrel for it to size the neck correctly, but you can remove the decapping pin function no problem.

They're super easy to get apart - it pays to give the top surface of the collet a clean and light grease periodically for best function.

I have a second mandrel without the decapping tail. I have never given any though to using the die without a mandrel but don't imagine it would go well a all. Try running a case through without it, let us know what happens.
