Problems with Remington 870 Super Mag jamming

I'm a newbie to shotguns and just purchased a Remington 870 Express Super Mag and I'm having problems with it not ejecting the spent shell correctly after firing. After firing I pull back to release the spent shell and instead of ejecting, the next shell to be fired ends up in the way and I can't pull the action all the way back. I've been able to get the spent shell out if I tip out the new shell and then release the action as if I'm firing for the first time, but I'm concerned that there's a problem with the gun not grabbing the shell correctly.

I only shot it for the first time today with only about 30 shells so it might be normal for a new gun, but I'm curious if others have had similar problems. It only does this some of the time so it's not very consistent.

Thanks for any help.

Sounds like there's a problem, possibly with the shell release latches.

Since this is a new gun, I'd contact Remington. I'm sure they will ask to have it shipped back for repair.
They have an excellent customer system on their web site at:
http://www.remington.com

Since this is under warranty, unless your gun dealer is an authorized Remington dealer, I wouldn't have it worked on locally, since this might void the warranty.

Let the warranty people handle it, sounds like the shell latches need adjusting....

I agree, send it to Remington.

One thought, are you shucking the gun with authority? If you shuck the too slowly/gently, it could cause some weird things to happen. If that's not the problem, then go ahead and contact Remington.

My wife's Uncle bought the Super Mag and took it straight out duck hunting. He had problems with it jamming like that all day. When we got back to the hotel that night, I asked if he had cleaned the packing grease off and he hadn't yet.

Did you clean the packing grease off?

BTW...after we cleaned it that night it worked fine the next day.

I went back out and put another 40 shells through it with no jamming at all. Turns out I wasn't pushing the action far enough forward to get the shell latch over the shell. After giving it a bit more oomph it seems to work fine.

Thanks for all the suggestions and help.

I just wrote Jshuck3 an email about this same problem I will post the email I wrote below, please read and give your opinons as well...

Hi, I just purchased a 12/26 Remington 870 express super mag from walmart and only shot about 75 rounds of Winchester super speed xtra 2 3/4 1350 FPS 1 oz. 8 shot. Anyway's I was reading THR forum and it seems I am having the same problem as you explained .This only happened maybe 3 times out of all 75 rounds, I would fire the shell and when I tried to pull back the pump it seemed to be jammed, also the "release button" under the trigger wasn't in function mode either, meaning it seemed to be sucked up inside so it had no "button motion" to let the chamber slide open. So since that wouldn't work I started to then give the pump more force pumping it back and forth till it finally came open and ejected the shell.

Now I was told these shells I was using are crappy and common for jamming in certain shot guns because it expands in the barrel because they are steel based shells.

I was also told to try out premium shells (AA's/STS/Nitro/Federal Gold Medals) to see where I stand meaning take it back if these don't work because will be more likely more then I would want to tackle "trying to fix the problem my self"

I am also being told that this 870 should eject all shells with no problems.

I bought this Shot Gun from walmart for 20% off of $267.00 for a total of around $214.00 because it was a return and needed repair for ejection problems but they said it was repaired.

Now I am wondering where you stand with these problems, did you send it back to remington? I am just trying to gather as much info on this as I can so im not stuck with a lemon 870. Any recommendations you can give me would be very much used. I don't know if I should just spend the money to get a brand new one or stick with it for the deal I got?????? Please help

Thanks,
Zac

Good to see someone 'doing their homework' and looking for what's already been written re. a problem/question.

Try cleaning the chamber thoroughly and polishing it with 0000 (4/0) steel wool wrapped around a bore brush and a shotgun cleaning solvent like Hoppe's. Sometimes that helps- if it doesn't, another trip back to Remington is likely called for- especially if the same thing happens when you try other ammo.

BTW, the action release button unlocks automatically when the gun is fired- it has traveled through its range of motion and has unlocked the action and cannot be pressed in any further. That part is normal, not being able to open the action when the action release is unlocked in not...

I was using some shells from my local range that my super mag did not like. Shells were expanding then not ejecting. Use the cheaper winchester's at wal-mart now with no problem.

I have been having the same problem with my 870 Express. I can shoot trap with light loads for hundreds of rounds, but when I shoot slugs or 00 full power loads, then the bolt is frequently stuck closed after I fire, and I have to really pull it hard to eject the shell.

I'll try the fine steel wool sanding idea.

I would fire the shell and when I tried to pull back the pump it seemed to be jammed,

I had this prob with 2 used 870s i got at differents times/shops.
I did the steel wool thing and it worked great on both. I just got a third 870 (used) and I am thinkin about jumpin the gun and doing this before I ever shoot it.

Had the same issue with about every 5th shell. Took mine to a local gunrange to shoot some clays and the onsite gunsmith deburred just inside the barrel with a dremel tool. He stated that remington had become the "Walmart" of guns so mass production and a tooling defect had effected many of the 870s. Ran about a dozen shells through it and never jammed again. Use it for a back up goose gun now. Beretta Extrema 2 has ruined me against pumps !

good luck
