Depriming Problem
Quote from Reloader on March 9, 2010, 11:37 pmSometimes the resizing die fails to remove the spent primer. It's beginning to happen more frequently, like 5 or 6 times per hundred. Each time I check to make sure the pin isn't broken. They don't appear to even have been moved. The second time around usually removes them. What am I missing?

Quote from Reloader on March 10, 2010, 1:52 pmIt sounds like the spent primer is sticking on the end of the decapping pin and getting partially pulled back up into the primer pocket. Take fine grit sandpaper and break the edge of the decapping pin so the spent primer is less likely to get wdged onto it.

Quote from Reloader on July 1, 2010, 1:15 amI have loaded thousands of rounds without a de-priming problem. However, lately, I too am having the same problem as the OP. Unfortunately, the frequency is much greater than his. More like one failure out of each ten.
I have already tried sanding the end of the pin to no avail. Any other suggestions?

Quote from Reloader on January 26, 2012, 5:10 amI'm having a similar problem, and it most definitely does not have anything to do with the decapping pin. Just for some context, I've had my press since 2004, and purchased it with the 9mm die set. I have since gotten the 45ACP and 38/357 die sets as well. I have loaded over 25000 rounds of 9mm with these dies, approximately 8000 rounds of 45ACP, and approximately 500 rounds of 38/357. I'm also an engineer, so I'm OCD enough to actually keep these kinds of records.
A few thousand rounds ago, I started noticing that 1 out of every 30-40 cycles of the lever, the primer wouldn't actually eject, so I'd have to remove the brass from the powder station so that I could repeat until the primer came out the rest of the way. By the latest 200 rounds, it was happening every 10-15 times. I checked the decapping pin, and found that it was noticeably shorter than a new one, so I replaced. The problem continued.
The next step was to cycle through the toolheads, while leaving the 9mm shellplate in place to see how the other resizing dies performed. Neither the 45 or 38/357 dies had a single failure to eject the primer. I also noticed a loud pop/click noise from the spring that I do not hear when using the 9mm die. I actually think I remember hearing the 9mm do that when I got it. But it's been years, so I can't be certain.
After that, I started rotating the pins between the 3 resizing die cores. Regardless of the setup, the 9mm core did not perform well, or make the clear popping noise, while the other two dies that have been used far less worked perfectly.
As far as I can tell, after all the experimenting, either the spring on the 9mm has cycled enough to start weakening, or there is something associated with the “snap spring” decap assembly inside that I can't see that is worn or fouled.
