jwhittin Posted February 29, 2020 Share Posted February 29, 2020 I'm scratching my head on this one. Hoping some more brain power will help. Just converted to 9mm. Using RCBS carbide die. Got everything dialed in and started reloading. Out of 100 rounds, 2 cases moved from the sizer/decaper (station 1) to priming (station2) with the spent primer completely intact. I checked the die and the decapping pin and both are solid. Odd thing is I've moved the pin down twice but it's still happening. Pin is below the die at least a half inch. If I move the pin down much more there is interference on the down stoke. Is it just a very sensitive adjustment? Anyone experience this?

Jmo2011 Posted February 29, 2020 Share Posted February 29, 2020 You may be experiencing primer drawback. Occasionally I see a primer get stuck on the decapping pin and it gets pulled back into the case. Might need to polish the end of the pin a bit.

MemphisMechanic Posted February 29, 2020 Share Posted February 29, 2020 (edited) On the Dillon pin it’s standard procedure to file the pin to a sharp point to ensure you don’t have primers drawn back in. I did it before ever using the die and never had a problem. Edited February 29, 2020 by MemphisMechanic Link to comment Share on other sites More sharing options...
Nevadazielmeister Posted February 29, 2020 Share Posted February 29, 2020 I agree with the others, it is likely primer drawback. However, just know that Dillon learned of this and upgraded their dies with a spring loaded primer decapping assembly on their sizing dies. Now, I never get primer drawback anymore, it simply kicks the primer out. It is just one of many reasons I always recommend Dillon Precision.

jwhittin Posted February 29, 2020 Author Share Posted February 29, 2020 That makes sense. I'll modify the pin and see if that solves the problem. Link to comment Share on other sites More sharing options...
Jsjac Posted February 29, 2020 Share Posted February 29, 2020 I also use Dillon die with the spring loaded decapping pin and it pops the primer off the pin. I have had no primers pulled back in with the decapping pin. I keep extra "E" clips because it breaks occasionally. Link to comment Share on other sites More sharing options...
3Dflyer Posted February 29, 2020 Share Posted February 29, 2020 I could not figure out my decapping issues that began suddenly. I was getting finished rounds with old primers still in place. Look what I found! The .22lr case and stuck primer prevented primers from being fully pushed out. The partially pushed out used primers would be set again on stage two when a new primer would reseat the old one. I quickly adopted better brass cleaning and sorting practices after this situation.

jwhittin Posted March 1, 2020 Author Share Posted March 1, 2020 That's definitely a new one! Thanks everyone! I filed down the pin diameter and it seems to be working trouble free now. You all rock! Link to comment Share on other sites More sharing options...
Postal Bob Posted March 2, 2020 Share Posted March 2, 2020 You may also have some caes that have crimped in primers. Whenever I have a spent primer not completely push out, it's always a case that has a crimped in primer. Link to comment Share on other sites More sharing options...
Dirtchevy841 Posted March 3, 2020 Share Posted March 3, 2020 After filing my Dillion dies no pullbacks at all. Link to comment Share on other sites More sharing options...
