Remington 870 locked up solid

[Roccobro]

What brand of shells?? Do you have a micrometer to measure a fired piece around the brass area?

The only major problem with 870's has been around forever and the real reason flexitab mod was made. The Range safety officer proved that when he banged the but and it opened and operated there-after. Missized or cheap low brass shells can jump the shell stops (sometimes worn)which lock the gun up solid with a shell on top of elevator with a shell in chamber and a shell wanting to feed from magazine. Cure, 1. bang butt stock hard while holding pump grip which forces bolt past shell On elevator 2. with flexi-tab mod pull very hard on pump grip and u-shaped cut in elevator and chamfers on bolt and carrier allows bolt to jump over round on elevator and return to operation.

Personally, I would add the "sticking chamber" as a flaw. I have a Beretta A391 and a brand new SLP that both blow through the wally world crap Winchester Universal, as well as Federal low brass and Remington low brass. The Win and Fed would choke all four of my 870's including one 870p. Not sure about the Rem.

I finally got the 870 running recently (after about 2 1/2 years owning it) by using a brake hone and then some 0000 steel wool with polishing compound. Now my 870 is as reliable as my autos. Kind of sad to be able to say that.

Going to work on two other Express barrels to get them fixed.

Those Experts would do it on my BPS. Now i shoot all Kents and Fiocchis for waterfowl, with a few black clouds thrown in. i still shoot cheap winchesters for informal clay shooting when its not going to cost me a bird if they jam.

long story short, just buy the cheap remington shells. i have a new 18" 870 that eats them all day long. and they are about the same, 20-25$/100 in 7 1/2 or 8 size, 1 1/8 oz 2 3/4 shell loads.

Had the same problem with my 870 Express. It was the cheap Winchester Value Pack shells form Walmart causing the problem. The same rough chamber issue. Alot of you will say just buy better ammo which is great fix to the problem if you can afford it. I do alot of clay shooting for fun not competition and to me cheaper is better as long as they fire. It'll dust a clay just as good as the premium stuff. Plus IMO a pump gun should cycle all makes of shells reliably, within reason. Took me 5 min. to polish the chamber and its never been a problem since and I still get to shoot cheap crappy ammo all day long and have a blast doin it.

Bears repeating...

If modern ammo used brass and decent QC standards, that would probably be the case. But, what most are saying is, it isn't the gun that's the fault, it's the ammo that is sub quality.

A while back, I read that the new Federal Judge loads use BRASS brass, not steel, because of the sticky ejection that steel gives the gun. Brass gives no problem. I figure same thing is going on here, sub quality QC of the ammo combined with steel for "brass". No, it's not the shotgun that needs proper QC here. Sure, any shotgun should feed all ammo, so lets make sure all ammo is made to decent standards of quality and that will happen.

I wish someone would come back out with Activ ammo, and especially in steel shot this time. Having no exposed "brass" at all would be GREAT in the salt marsh. No more rust.

Folks in the time since Christmas the gun club has seen a lot of new remington 870's, among others coming out to shoot skeet or trap. I have personally helped un-jam 3 seperate 870's and one 500 mossberg. All of them had 3 things in common. Only one shell was loaded, they were new guns, and last but by no means least cheap walmart winchester universal ammo. The 500 and one of the 870's were unjammed by tapping the butt on the ground while holding the pump handle. One of the 870's extractors ripped the edge off the shell and had to be disassembled and the shell was shoved out with a cleaning rod. The remaining one was left setting about 30 minutes outside in the 20 degree weather with 10 mph wind and came out with some effort applied to the pump.

It became clear to me that these shells have poor quality control and are not sized properly after checking about half a box worth in the chamber of a doubles gun and finding over half of those wouldn't go in without some force.

Yeah, if you want a gun that will feed any crap you buy, get an H&R single shot or a good double barrel. Otherwise, you just have to buy quality ammo and live with it.

Look inside the reciever and at the extractor and where the end of the

extractor is riveted. If I'm not mistaken the extractor lies in an

elongated "cup" or machined slot that the extractor lies in and it is possible that the end of

the "cup" or slot is jutting out enough to catch the edge if the rim and not

letting you pull back the arm to eject the shell as the shell swells upon firing.

I think that may be a possibility as I've encountered this with an 870 a while

back. What I did was to take a dremel tool and grind it down some and after

doing so , the gun cycled without a hitch.

I hope that you find out what is going on and this is a slant to what may be afflicting your shotgun.

Hope this helps!

Or an SLP or an A391... I find it ironic that those too unreliable for home defense autos chew through all that sub standard ammo yet the iconic pump gun can't. Dunno, but that doesn't wash with me. The 870 should be the #2 pencil of shotguns. Also, if rather minor work can be done to alleviate the issue, it doesn seem to indicate that the gun manufacturer isn't interested in making their product as reliable or usable as it could be (cost not withstanding).

Or just EASILY fix your damn pump gun....
