Today while dove hunting my 870 got stuck in battery.  Hard slam on the ground while holding slide broke it free.  Didn't happen again but Im curious what might have caused it.  Breaking down and cleaning it all up for tomorrow just to be sure but it wasn't dirty or anything.Anyone got an idea wtf happened?

Polish chamber, check youtube. (I've had this problem)

Remington has been having issues with tight chambers for the past few years. I've had about a dozen over 3-4 years come through my shop that needed to go back to Remington to have the chambered re-cut because it was out of spec.
Sometimes a solid cleaning with a brush will help loosen it up.

I had a problem with my 870 that made it difficult chamber another round, like the slide would just stick. Stripped it all the way done and cleaned it up and it ran like a top after that. A good scrub would be a place to start.

Yep.

Cheap rounds get stuck in my 870s chamber.

Can't shoot the cheap bulk packs from w/m. Defensive loads... Buckshot and slugs work fine. When i shoot clays I have to get the high end loads...

Yeah, polish the chamber is the answer...

Or... If you are like me and think you will screw it up... Buy the pricey bird shot...

When I do have to shoot the cheap stuff, If I wait 10 seconds, it will extract just fine... Seriously.

Maybe I should just polish the chamber...

El Cheapo Winchester birdshot jammed mine up like that. I think they were "SuperSpeed" rounds. Nothing else has ever done it to me.

Apparently, not an isolated incident. I did some digging, and found multiple tales of 870s choking on cheaper Winchester shells. Supposedly, they're often out of spec

I've been shooting a Wingmaster I bought in the early '80's. (1981? at K-Mart, maybe 269 bucks?)

No mechanical problems whatsoever, that I myself didn't cause.

Sometimes after multiple shots or when the gun heats up, rounds (especially cheap-ass birdshot) it will freeze your slide forward and you have to grab the pump and beat the shit out of the stock to get the gun to unjam itself.
Try more lube.

While an 870 is a decent hunting arm that stands up to a low to moderate amount of abuse or usage before failure, I'm really hoping that you're not relying on one for self-defense.  
Much like 1911s, no matter how much your 870 costs---whether it's a hunting or decked out as a defensive arm, they all fail in the same places.  Simply put: Don't trust your life to one.  Ever.

polished  and cleaned up the chamber.  shitty machining. burred edges everywhere. it had the ridge defect where the rim of the shell was getting caught . cycles like butter now.

Yeah... Um...

I have indeed had trouble with cheap bulks backs from wal-mart in my 870...

Never had an issue with the higher-end stuff.

Never had an issue with defensive loads.

Trust my life, and the lives of my loved ones to my 870 loaded with defensive loads...

Perfect? Not in every situation. But it is 100% trusted in my home...

Welcome to owning an 870. We teach that in the academy, since they are known for locking up.

Well, bless your heart..

If it's not too much to ask, would you mind describing how you came to be such an SME? I don't mind learning when I'm wrong; I just won't take your unsubstantiated word to put my 870P under the bandsaw.

Well, I bought an 870 express 12-guage last summer from Wal-Mart.   I have only shot it a few times and only used Federal Police Tactical 00 buckshot and Hornady TAP 00 buckshot.   Both of these have worked flawlessly.  

I AM NOT the world's authority on shotguns but it sounds like an ammo-based problem to me.  The youtube link showing the polishing of the shell chamber seems a good idea to me.   IF I ever have any problem of this type, I will get out the dremel and a cotton polishing pad and CAREFULLY do this.
9/3/2013 8:19:26 PM EDT

This is a common 870 problem.  In the late 90's I witnessed the purchase of a youth model 20 ga that did the same thing but on every shot.  The gun was brought back to the store and the purchaser was told to try higher grade ammo.  The higher grade ammo did the same thing but got stuck to the point of not being able to eject the shell at all.  The gun was then brought back to the shop with a spent shell still lodged in the chamber.  The shop did the right thing and exchanged the gun on the spot.  Unfortunately the new gun had the exact same problem and the shop ended up giving the purchaser (a family member of mine) a full refund.  I have a 12ga 870 that hangs up every 1 in 30 shells but I just deal with it.

I have an Express from the late eighties that has never, never or should I say never, mis-fed, locked up or had a failure to eject.
This shotgun has a body count higher than Saddam and keeps going.

I even fell in a river with it once and just a little while later shot a pig in the face with it from 10 feet away.

When the extractor pulls on the rim, it cocks the shell slightly. Just outside the chamber is a burr or a ridge, where that cocking of the shell pushes the side opposite of the extractor into a groove before the ridge. Smooth all that out and you won't have to mortar your shotgun anymore. I saw this over at shotgunworld.com.

I had that happen and it turned out that the rear sight that was installed had a set screw that was about .5millimeter too long and was rubbing top of bolt.
