Spent primers not dropping free from decapping pins
Quote from VinnySem on September 24, 2024, 6:06 pmI use a few different decapping dies, the Dillon universal, Lee universal, and Hornady decapping/sizing dies. I frequently have primer "pull back" or whatever it's called, where a spent primer will stick to the pin and get pulled back into the pocket, blocking the new primer from being seated. Anyone have any tips on how to eliminate this?

Quote from duvallmark on September 24, 2024, 8:45 pmI have only seen this a couple times in 30 years using Dillon 550. Went away when I got the decapping die appropriately adjusted. Die depth relative to shell plate. See the manual for details or the video. Having said that I have caliber specific decapping sizing dies not universal ones. This for Pistol or rifle? I full length resize rifle brass with usually a small base resize die.

Quote from VinnySem on September 24, 2024, 8:50 pmThe die is properly adjusted, threaded in until just touching the raised deck. Decapping pin extended about 3/16" measured with digital calipers. Happens on both pistol and rifle rounds of all calibers.
I read elsewhere that it could be from wet tumbling brass without being decapped first, which I did with a huge batch of brass harvested from my club. Wet tumbled then dried in a dehydrator.
I also read that there could be a burr on the pin, and to take fine emory paper to the point of the pin to smoothen it out.
I will give these remedies a try.

Quote from The Human Manual on September 25, 2024, 4:19 pmThe Dillon handgun dies have a spring-loaded depriming assembly to help reduce this. There are two different ways to help reduce this further. You can taper the tip of the pin so the fired primer is less likely to get wedged onto the tip of the pin. Alternately, you can flatten the tip of the pin so it doesn't go as deep into the fired primer. Both help, nothing is 100%.
