550 die alignment

[Pat B.]

I have toolheads and dies for the .40 and .45 that run flawlessly..  Several thousand rounds ago I set up for 9mm..  I'm having issues with the Dillon resize die.. Ten percent of the primers fail to stay ejected from the case after sizing..  I tapered the knockout pin quite a lot but still have problems..  Sooo, I've run both a Redding and a Lee resizer. Neither have the primer issue but neither allows unimpeded flow of the work.. After turning the star on the shellplate the case almost always doesn't quite line up with these sizing die.. I have to give the shellplate star a tiny nudge to get it lined up so I can raise the ram...  Do any of you knowledgeable folks have any advice that might help me solve these little problems?? If I could solve the primer problem with the Dillon die I'd be fine.. Or if I could solve the alignment issue with the other size dies --- I'd be fine...

Thanks in advance !!

After messing with the Dillon die several times I think I have now solved the decapping pin issue.. As I mentioned, I had tapered the pin but from another thread saw that you needed to also put a radius on the point, no sharp edges..  Seems to have worked..  Thanks all..

That's good that you fixed it. Inahd the same problem but with hornady dies. I switched it to a Lee resizer die and never had that problem again. I probably need to taper the pin as well to make the hornady one work.
