the decapping pin should be replaceable- or at tleast it is in my 308 wcf dies- undo the knurled knob on the top and the entire stem should come right out- on the bottom of that stem you'll find a collar - tighten that down and it should hold your decapping pin- btw, if you can't find decapping pins, you can use a finishing nail and grind the heand and point off- it's not the best solutiuon, but it works
