I've never seen this happen, but during depriming (Lee universal decapping die) primers are breaking in half and getting stuck in the case.
Anyone know what's going on? *Edit - these were not wet tumbled*  Attached File |

Are you wet tumbling before decapping? If so, corrosion has chemically welded the primer body to the case.

I always dry tumble before decap to avoid this. Moisture gets em stuck

Yep, worst deal I ever got. A buddy found a “deal” on .30 carbine that we split. Stuff was washed with primers in which wasn’t disclosed. The decapping pin would stab right through the primer as the skirts were bonded to the pockets. Green nasty pockets. It sucked!

OP has found out why many of us decap before wet tumbling
Whoever you got the brass from, skipped this step. Or didn't know any better. |

Might try soaking the brass to see if it’s enough to free up the primers when decapping. Try a couple to begin with to see if it works or not…

How many times has that case been reloaded?
I've never had any issues wet tumbling pistol brass, then progressively reloading later. I do take the extra step and dry them in the oven so they don't corrode. |

They have been sitting in a bucket for about 2 years |

Quote HistoryOriginally Posted By Trollslayer: Is this why so many have a LEE APP, to use as a decapping station? In this thread we find out wet tumbling was not involved, but the storage method may have had an effect. Fired primers and moisture can also cause corrosion causing the primers to not decap normally. |

Quote HistoryOriginally Posted By dryflash3: Correct. In this thread we find out wet tumbling was not involved, but the storage method may have had an effect. Fired primers and moisture can also cause corrosion causing the primers to not decap normally. I'd guess around 100 cases so far..... Anyways lesson learned that if I pickup wet range brass to process it right away. Thanks for everyone's help. |

The problem I have with the Lee decapping die is at times the primer will stick to the end of decap pin and get pulled back into the case when I'm processing brass on my Dillon Super 1050. Most of the time as soon as that case hits the swaging station I can feel the difference in handle pull. Anyone else has had this problem and is there a better repacement decap pin to use?

Frakford Arsenal X-10 has 10 stations and uses one of them as a second decaping station for this reason. The next swages the primer pocket. I have had it happen on a 650/750 a very few times. On large high pressure rifle cases. I have never had it happen on a DSB. I have not loaded 9mm or anything that might have a crimp on the primer though |

We're the cases ever cleaned with anything containing ammonia? Anything else that promotes corrosion?

Quote HistoryOriginally Posted By AeroE: We're the cases ever cleaned with anything containing ammonia? Anything else that promotes corrosion? To my best recollection this batch I'm going through was shot, picked up and tossed into the twice fired bucket. I have t even cleaned these yet, so far I'm through about 5-7 gallons and have just hit this snag. Not sure how many more I'll hit.....it's very possible It was rainy, snowy and cold when some of these shooting these and I just tossed them in that day. Thinking about it, it's possible I picked up some range brass and tossed it into this pile. I guess I got my answers (wet/moisture = corrosion) and will just have to move forward. |

Quote HistoryOriginally Posted By ZA206: Possible solution . https://www.mightyarmory.com/products/the-pua-decapping-die-for-lapua-brass Just didn't work on the 1050, primers would decap and then reseat, works great on a single stage or an APP. My issues disappeared when I got a Mighty Armory decapper. Ya it's $80 but it's worth it to have all decapping problems go away on the 1050. |

Work through the bucket, get it clean, and move on is about all you can do. Not much moisture is required to cause brass to corrode. Add plated primers in contact to set up galvanic corrosion. |
