Boulder Canyon Bob# 32052L Posted March 27, 2019 Share Posted March 27, 2019 All of a sudden I'm getting primers separating when I deprime my brass. Brass is Starline used, but number of times ,loaded varies, Federal large pistol primers, caliber is 44-40. Out of 100 pieces of brass I got about 15 that this happened on. The sides or anvil stays in the brass and the top is ejected , of course a new primer can't be seated. Hate to just recycle the offending pieces, but thought I'd check and see if anyone else has run into this. Link to comment Share on other sites More sharing options...
Three Foot Johnson Posted March 27, 2019 Share Posted March 27, 2019 Odd. Doesn't usually happen, unless it's crimped military stuff, or old mercuric primers that have corroded. Link to comment Share on other sites More sharing options...
DDD, SASS 28309 Posted March 27, 2019 Share Posted March 27, 2019 Check the depriming pin for a round point. When they get sharp they will do that. Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted March 27, 2019 Share Posted March 27, 2019 Bad lot of Federal primers, most likely. Folks reported having this same problem with some Federal primers a few years ago. You can usually pop the remainder of the primer out of the pocket with a sharp tipped awl. Good luck, GJ Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted March 27, 2019 Share Posted March 27, 2019 Do you wet tumble before repriming? OLG Link to comment Share on other sites More sharing options...
Keystone, SASS # 47578 Posted March 27, 2019 Share Posted March 27, 2019 Well, I thought I was the only person having this issue. Never noticed the separation of the anvil & cup when depriming on 1st stage of the 550 Dillon and dry media tumbling. I now deprime with a universal decapper prior to wet tumbling. Have to hit some primers twice to dislodge the primer parts. The pin is rounded and have tried adjusting the pin depth without any positive result. I believe the primers are seated more firmly & to the bottom of the primer pockets without the usual debris from powder & primers. Link to comment Share on other sites More sharing options...
The Rainmaker, SASS #11631 Posted March 27, 2019 Share Posted March 27, 2019 I didn't get the impression that the anvil and cup were separating (that happens to me all the time and seems normal as they are two separate pieces), I thought BCB meant that the cup was actually coming apart.

TN Mongo, SASS #61450 Posted March 27, 2019 Share Posted March 27, 2019 I've used a primer pocket brush and primer pocket reamer in the past to help alleviate that problem . I've had the opposite problem more recently. Some of my .38 brass is so old that the primer pockets don't hold the primer firmly. Link to comment Share on other sites More sharing options...

Ringer Posted March 27, 2019 Share Posted March 27, 2019 Never had this problem until I bought some wet tumbled brass. Looked like new but almost 10% of it was ruined depriming. This was bought from a range. Wet tumbled with primers still in it. I'll ask for uncleaned next time and pass on their wet tumbled. Link to comment Share on other sites More sharing options...
The Rainmaker, SASS #11631 Posted March 27, 2019 Share Posted March 27, 2019 I dry tumble, but I would think that wet tumbling would be best suited to de-primed brass. Specifically to clean the primer pocket. Thoughts? Link to comment Share on other sites More sharing options...
Tex Jones, SASS 2263 Posted March 27, 2019 Share Posted March 27, 2019 I would take out the stuck pieces, as GJ said with an awl, and then use a reamer to clean out the primer pocket. I have used a Lyman case prep unit to ream out primer pockets, and it is amazing the amount of crud that comes out. Now, I use the reamer attached to a RCBS accessory handle instead of the motor driven reamer on the Lyman unit, as it's easier and I don't ream out any brass from the primer pocket.

Cheyenne Ranger, 48747L Posted March 27, 2019 Share Posted March 27, 2019 ►wet tumbling with primers still in will cause this to happen as will very old brass. Once deprimed though, the cases do fine ►Some folks say the wet tumbling cleans too much of the carbon out of the primer pocket making it hard to reload new ones. I just mist them, primer pocket up with some case lube--problem solved. Link to comment Share on other sites More sharing options...
Keystone, SASS # 47578 Posted March 27, 2019 Share Posted March 27, 2019 Well, I wonder if the condition of the primer pockets depends on the length of wet tumbling. I usually wet tumble about three hours for 45 colt brass. The seating of primers since beginning wet tumbling is very positive and I never a high primer on my 550. Prior to wet tumbling the feel when priming was inconsistent and primers were not set as deep in the pocket unless I occasionally cleaned the pockets manually to remove powder & primer residues. PS I reload with Trail Boss powder, 6.1gr & 200gr RNFP bullet with a good crimp. Link to comment Share on other sites More sharing options...

I briefly tried to pick out the stuck pieces to no avail. I then put them back in the tumbler for 3 hours thinking it might clean them out, still no joy. I tried using a hand held primer pocket reamer, but that made no difference. It's like they're glued in somehow. Gonna set them aside for some time when I have more patience (Yeah like that'll ever happen). Thanks for the responses. Link to comment Share on other sites More sharing options...

Yusta B. Posted March 28, 2019 Share Posted March 28, 2019 Did you oven dry cases or let air dry. The latter can cause corrosion & possibly cause primer cup to stick to pocket walls. Link to comment Share on other sites More sharing options...

Then break out your broken screw extractor of the right size (even if you have to grind the tip off one) and extract the brass shell of the partial primer!

Yusta B. Posted March 28, 2019 Share Posted March 28, 2019 Any chance these particular cases were sitting around for a lot longer than normal after tumbling? Were they loaded with BP ? Link to comment Share on other sites More sharing options...
John Boy Posted March 28, 2019 Share Posted March 28, 2019 Bob - you have received many suggestions why but not these two: 1. The full length sizing/depriming die in the 44-40 die set is not properly adjusted per the instruction sheet 2. Buy a Lee Universal decapping die. It will deprime any caliber up to 50 caliber. This is they only decapper die I use and have never had anvils still in the pocket. In my case probably 75,000 or more including 44 WCF's Link to comment Share on other sites More sharing options...

When I did that I had problems with FTF, but the cases may not have been dried enough. Now I de-prime first then wet tumble, after that my OCD kicks in. First I get all the pins out then I blow compressed air into every case to make sure it's dry. After that I let them sit out in the shop for a couple of days and spray a little case lube on them before put them away. BTW this is for .45LC.
