Going back 40 some years I had trouble with jam ups with my 12 Ga. pump shot gun. I noticed that the ammo I was using was low brass so I changed to high brass Super X . No more jamming problems. It’s inherent in pump shotgun’s as I recently acquired more pump shotguns. Same problem occurred.

I had the ejection issue with my Mossberg 590 mariner. These things also used to jam in my Benelli Nova, and a friend’s Mossberg 500. I have not experienced any issues with the 100 packs of Federal. Buckshot and other high brass Winchester rounds I have tried cycled fine. Only Winchester Universal has given me problems. In all three of these pump guns they did the same thing; they got stuck in between the extractor arms.

Old Winchester model 12 16 gauge. Bought a box of Win shells from Walmart just to shoot some clays. Shot fine but wouldn’t eject at all. Had to take gun apart to fix. Federal ammo worked fine. can’t use win ammo in a win gun? Seriously?

Sooo glad to see everyone having the same issue with the winchester ammo. I’m a beginner and went out today to shoot some clays and made it through 4 shells of a brand new box i picked up from Walmart,and every shell after that jammed. I thought maybe i had done something wrong or not maintained my gun well enough and was getting worried until i read this. I had a box of federal shells last weekend and didn’t have a problem. Guess I’ll stick with those from now on. Should have known you get what you pay for,there was a reason those winchesters were so cheap.

Was at the range tonight shooting bird and buck though the Mossberg 930. Winchester 00buck wouldn’t chamber correctly. Kept getting stuck half way on autoload, and had to manually force it on every shell. They look a little swollen. Ejecting works fine however. But I’m nervous about having them around.

UPDATE: I recently contacted Winchester Ammunition regarding their shells and they’ve asked me to send them back for quality testing and will send a check for reimbursement. However, I don’t have any more of their shells. If you still have a box or partial box of shells that were jamming, let me know and I’ll send Winchester your details. They’ll send UPS to pick up the box of shells, no charge to you.

It is 2016 and we are still having issues with those Winchester shells. This passed weekend two Mossys were jamming with them. I’ve also had problems with my 870 before I stopped buying them at all. I’ve also had a few hard primers in both the Remmy and Mossy, so I knew it wasn’t a gun problem. We’ve switched to the federals with no further extraction problems. I expected more from a reputable company.

Hi James, You might try using Federal shells instead of what you’re using. If you’re using Winchester, there have been a lot of people having issues with ejecting their ammo. If that doesn’t fix the issue, if you haven’t cleaned your gun in a while, give it a good cleaning…but I’m almost willing to bet that it’s the shells you’re putting through it.
