austex Posted December 23, 2013 Share Posted December 23, 2013 (edited) Had a bizarre malfunction during a match today. Engaging a target, first shot OK, second shot "click." Racked the slide, round ejected, but then "click" again. Tap-rack, another "click." Dropped the mag, reloaded, and went on with the stage. Afterward, came back to the mag and found the ejected round. Apparently, a primer fell out of a round as it was chambering. It jammed the bullet below into the mag! Out of 40K or more reloads, I've had maybe 2 or 3 loaded rounds with loose primers make it into QCed boxes ready for a match. But after today, I may tumble loaded rounds a while to make sure it doesn't happen again. Edited December 23, 2013 by austex Link to comment Share on other sites More sharing options...
grapemeister Posted December 23, 2013 Share Posted December 23, 2013 It'll be interesting to read the replys to this topic. I've never had a problem with primers falling out, and it will be interesting to learn what may cause that to happen. Are you swaging all your brass, by chance?

joshxdm9 Posted December 23, 2013 Share Posted December 23, 2013 Yeah thats first time I have ever heard of a primer just falling out of a case. Not sure I would tumble loaded rounds! Link to comment Share on other sites More sharing options...
Ronnie j Posted December 23, 2013 Share Posted December 23, 2013 Russian primers? Link to comment Share on other sites More sharing options...
austex Posted December 23, 2013 Author Share Posted December 23, 2013 Russian primers? No. Winchester small pistol primers. I shoot open a lot, too. After a while, the pockets get larger from the pressure. It's not a huge problem, and I usually feel it while loading. Link to comment Share on other sites More sharing options...
Solvability Posted December 23, 2013 Share Posted December 23, 2013 I have had this happen and also thought about tumbling - might work. Link to comment Share on other sites More sharing options...
Sarge Posted December 23, 2013 Share Posted December 23, 2013 those 9mm pockets eventually get loose especially after loading them to MAJOR PF. I load 9MAJOR and I too can feel when the pockets start getting looser. I tumble mine anyway but the only time I caught one falling out was when I stored them in ziplock bags and all the jostling made one fall out.

CarRacer Posted December 23, 2013 Share Posted December 23, 2013 Start segregating your major PF brass to prevent this in the future? Link to comment Share on other sites More sharing options...
dafdov368 Posted December 23, 2013 Share Posted December 23, 2013 Ive ran into the problem from unwanted brass at a local IDPA match. Im 100% sure it was just bad brass because i had at least 15 primers fall out of a batch (2k) I had loaded . Link to comment Share on other sites More sharing options...
BillD Posted December 23, 2013 Share Posted December 23, 2013 (edited) Yeah thats first time I have ever heard of a primer just falling out of a case. Not sure I would tumble loaded rounds! How do you think we get those nice shiny factory rounds? I've tumbled to remove case lube for maybe 80,000 rounds, haven't shot my tumbler yet.

cecil Posted December 23, 2013 Share Posted December 23, 2013 I shoot 9mm MINOR.. was shooting a practice match & on an ejected round to "unload & show clear" I found that round the primer had fallen out .. i always de-prime all my brass on a RCBS rock chucker press before tumbling... and when i notice a brass that de-primes easily.. i discard that brass.. but evidently i missed that one.. from now on i will pay more attention to my de-priming..

jcc7x7 Posted December 23, 2013 Share Posted December 23, 2013 I tumble after I load if the lube is messy. but little by little switching over to Bayou and SnS coated bullets, same product different color for different calibers Link to comment Share on other sites More sharing options...
ltdmstr Posted December 23, 2013 Share Posted December 23, 2013 No problem with tumbling loaded ammo. Like others, I do it to remove case lube, etc. As for finding missing primers, why not just put the ammo in MTM or similar case and give it quick look? Should be easy enough to spot.

Sarge Posted December 23, 2013 Share Posted December 23, 2013 seems like primers sometimes have to be jarred pretty good to get them to fall out. Putting them in an ammo box only says they are in there from loading. Recoil will pop them out which is how they end up jamming up guns and mags. Tumbling should expose loose primers before they ever make it to the mag. Link to comment Share on other sites More sharing options...
ZackJones Posted December 23, 2013 Share Posted December 23, 2013 Look closely at the picture. It appears the primer is wedged in the magazine. Assuming so that means the primer was at least seated into the case when it was loaded into the magazine. Link to comment Share on other sites More sharing options...
ltdmstr Posted December 23, 2013 Share Posted December 23, 2013 If the primers are seated and coming out due to recoil, I doubt tumbling is going to do the job. Have you tried rolling in Case Pro? Link to comment Share on other sites More sharing options...
dauntedfuture Posted December 23, 2013 Share Posted December 23, 2013 I think it's more likely you missed priming a few. If you are not using carbide dies then get one and do without the lube. I have missed priming some too. I have never had a primer come out of a .223 case in the tumbler full of loaded ammo. 9mm major is hot but.....

BillD Posted December 23, 2013 Share Posted December 23, 2013 (edited) After firing some .45 cases until you couldn't read the headstamp, I've never had this happen to me. Is this a 9mm Major thing? My bad, I see the minor mentioned up above. Edited December 23, 2013 by BillD Link to comment Share on other sites More sharing options...
BillChunn Posted December 24, 2013 Share Posted December 24, 2013 I also shoot 9 Major in nickel cases and have had primers jar loose in the magazine. For a majority of the time I find that Speer cases are the worst. For matches I've gone to new brass. 6.6 grains of Winchester AutoComp under a 124 / 125 grain Montana Gold hollow point at ~170 power factor. It's still a PITA when it happens in practice.

sarpau Posted December 24, 2013 Share Posted December 24, 2013 I haven't done so but know a couple guys who place their ammo in their ammo box, bullet down, and dab nail polish on the primers. Quick wipe before it dries and it creates a ring/seal around the primer and removes all excess. Essentially gluing them in place. I may give it a shot at some point.

Gandof Posted December 24, 2013 Share Posted December 24, 2013 I run into loose primer pockets in 9mm brass frequently. I load on a 650, so I usually catch them by feel when loading. Occasionally, I miss one, only to find it at a match when I'm loading magazines. Tumbling after loading might just a good way to prevent the problem.

I'm curious because I've never had the problem with primers coming out, but I've only loaded minor. Seems like I would have had at least one come out over the years since I use range brass, and I'm sure I've picked up some brass along the way that's been reloaded at major power factor, or have I just been lucky. So far, seems like it's the 9mm major crowd that's having the problem. Edited December 24, 2013 by grapemeister Link to comment Share on other sites More sharing options...
Red Ryder Posted December 24, 2013 Share Posted December 24, 2013 If the primers are seated and coming out due to recoil, I doubt tumbling is going to do the job. Have you tried rolling in Case Pro? I started Case Pro ing all my brass. I have noticed a significant decline in loose primer pockets with all the "open" range brass that I pick up.
