Holy Cow batman, I was removing the primers my first batch of rounds when the end ring pulled clean off. I was able to remove the deprimer from the die and tried to use a punch to knock the blasted thing out and succeeded in removing the bottom of the case so I tried a tap and still wouldnt come out, I dont give up so I had a idea I took a can of compressed air and sprayed liquid on the brass and got it real cold and from the top sprayed wd40 and ya know it actually worked. First thing I did was completely clean the die with hoppes removing the oil and brass shards, fortunatly no damage was done to the die but it sure was stuck.
I will never make that mistake again either just in case i did order a new set of dies to have on hand as backups. Watching Burn notice sure saved the day before that I didnt know canned air turned upside down and sprayed on a object would get it very cold just watch you fingers lol
I have had that problem with some of the brass that my nephew (in the Army) brings home to me. I didnt recognize the headstamp and for the longest time couldnt figure out why I couldnt deprime until I pushed my decapper stem out the top of my die....glad I didnt break it.My range pick ups have at least five different headstamps. Even if there isn't any difference in consistency I'll probably start being a little more selective in what I take home.
On Monday I picked up four or five cases of what I think are Barnaul headstamp which had undersized primer flash holes. I ended up tossing them in the trash since I couldn't decap them.
