    I dont know why this is happening, but all of a sudden my Remington 870 Police ((wood stocks)) stopped extracting shells. Before Today,..it was working like a dream.

    Im not a gunsmith so I dont know why this is happening. I can speculate this:,...

    The extractor does not appear to be going fully into Battery,..or the extracter claw Hooking onto the rim of the case. As a result,..there is that tiny bit of headspacing causing the shells to bulge when this shotgun is fired. ???

    It appears that when the shotgun is fired that during the recoil process, the rim of the shell casing is slamming into the extractor. This is why you see the mark/fingerprint of the extractor dented into the rim of the shell casing.?? But I may be wrong. Imnot a gunsmith.

    First things that come to mind would be a very dirty chamber causing the hulls to stick, a work/weak/misaligned/bent extractor, or a weak extractor spring. I don't know shotguns as well as I do ARs, though. Plus, I'm a Mossberg owner, not remington. Aippi will probably have more insight, but those three things would be my initial reaction.

    Edit to add: Something definitely looks "off" about that extractor to me. Again, I have no basis for comparison for that, and it could be perfectly normal for an 870... but it doesn't look right to me.

    Is it doing this with other ammo?

    It appears to be doing it with other ammo. I fired the Fiocchi ammo which has the dark brown shells then switched over to the red shell casings. I forget what make they are. They have a wreath on them with 3 3/4-1 1/4 markings. On the brass they are marked 12 GA Made in USA.

    The interesting part about the red shells is that they dont appear to have the extractor strike marks on the brass, yet they bulged and failed to extract.

    Shoot some regular Remington, Winchester or Federal stuff and tell me if this is happening. I don't know what kind of ammo that stuff is and can't tell you what is going on till I know it is not an ammo issue. Once I know, I can help you as I am Factory Certified on you 870P and do this for a living.

    Check into the extractor relief (cutout) next to the chamber. Use a "hook", or something sharp to make sure nothing is plugging up the cutout while the bolt is in battery. That extractor may be contacting something that is not allowing the hook to spring back against the brass rim. Just a thought.

    A lot of people are saying the action is smoother with the 870 over the Mossberg 500. I have 2 870's and 2 Mossberg's (500's) and the action on the 500 is much smoother than the 870, at least mine are. But I love them all! Either is a great choice.

    Thanks aippi, I appreciate youre help. It turns out the red shells with the wreath on them are ESTATE, 2 3/4", #6 shot.

    Ill shoot the Remington/Winchester/Federal stuff and get back to you when I can.

    390,...the barrel is stamped * 12 GA 2 3/4" OR 3"

    so this shotgun can handle 3" shells.

    tenntornado,..the cap is tight now. I didnt check its tightness before firing as its never been an issue before. The last time I shot it, I broke it down cleaned it and everything was put back together again tight.

    That ammo says that it's the "Ultimate In Performance" so I doubt it's the brand of shells. Are you using a tactical lube on your gun?

    It can be anything from ammo to a broker ejector. Starting with the simple is the only way I can help when I can't see the weapon nor talk you through checking things.

    IIRC what the barrel is stamped in irrelevant on the 870. It depends which receiver you are using. Any of the receiver's marked "Magnum" are suitable for the 3" shells. And your 870P is so marked. Also IIRC the only ones that aren't marked "Magnum" are the older light weight receivers.

    I cannot offer whole lot about your trouble, but your 870P sure looks nice with the woods.

    I offered to assist you if you call and have the weapon in front of you. You have not. Can't do more then that as there are things to check on the weapon and I can't see them.
