I have NEVER EVER seen a LEE decapping pin break. Are you sure it wasn't an RCBS decapping die?
The RCBS pins are solid, and don't budge. If you bump into something solid, they either break or bend horribly, requiring replacement!
The LEE decapping pins, on the other hand, are set in a collet, and if it bumps into something solid, it merely slides up into the collet, requiring only a reset of the pin. I've never seen one break.
Military brass has the crimp, and that has to be dealt with, BEFORE re-priming. So, I do the decapping (without resizing) with a universal decapping tool (Lee) off line, then run them all through the Dillon Super Swage offline, and then reintroduce the brass to the system, and let it rip!
