Before I have to start digging shrapnell out of my face, I have a question???
I recently neck sized and de-primed some cases with a dodgy die (Lee!).
Having then trimmed and re-primed them, it became apparent that the heads were too loose on some of them.
I now have some new dies (Redding) and I'm wondering if I can de-prime live primers and neck size safely?
Also, is it possible to remove the de-priming pin and just re-neck size. Trouble is, if I do that I'll not be able to trim again!
Any thoughts or experiences?
