870 extraction issues...

[omgwtfbbq]

Recently my Remington 870 Express has had problems extracting spent shells. The extractor grabs the shell base fine but it just wont pry it out of the chamber. Then if I let the gun sit for about ten seconds and try again, the shell usually cycles fine. I can't tell but it seems as though the shells might be swelling or something and making it hard to extract.

It was doing this more with cheap walmart ammo so I tried varying the shell brand and quality, and I found that there is less jamming with the higher quality shells but there is still the occasional stuck shell.

I tried searching the archives and came up with nothing. :/

Any ideas or am I doomed? Thanks ahead of time.

you are not doomed

this has happened to others...but i forgot the solution. Something about polishing something or another

but rest assured, youre going to be okay

Is this a new 870 if so this is I guess normal but not really. It is a manufacturing flaw where the chambers are to tight. I have heard of people using steal wool and buffing it out ( I did not try this method on mine and had the same problem with both of my 870's). The issue went away on mine after about 75 shells down the pipe of both steel shot and magnum shells.

remington knows about the issue - take it to your local authorized remington gunsmith and he should know the deal - polishing the barrel camber - and he will bill remington, no cost to you. the issue is the parkerized coating on the 870 express causes some of the barrels to be out of spec, and cheep ammo makes it worse

Excellent guys. Thanks a ton.

Just need to locate an authorized gunsmith. I'll ask around and see what I can shake out. I wouldn't mind homebrewing it if necessary but if it's a free fix, I'll take it in.

WHAT???? The inside chamber is Parkerized? Since when?

You can reslove the issue and have some inexpensive excellent cleaning tools for maintaining your weapon. Get a couple 7/16" ( or 3/8 if your drill is small) hard wood dowels. Get a package of the 00 or 000 steel wool. Take one of dowels and strectch a full pad of the steel wool over the end of it and tape off the bottom. It should look like a large Q-tip. Put this in your drill and spin it in the chamber till you feel the barrel getting hot for the first time you do it, when cleaning latter a quick sping will polish it. Problem over. Take the other dowel and strectch 3/4 of a pad over it, this one will be smaller then the one for the chamber as it is for the bore. Use this each time you clean the wepaon and the barrel will look like a mirror inside. You can also use the chamber one to polish the mag tube. You can see this tool on my web site www.aiptactical.com in the How to Video "Tube Extension Kit"

This.

I've done the same thing with a cleaning brush wrapped in 0000 steel wool moistened with a little oil. Use a single cleaning rod section and your cordless drill. Clean well after the polishing.

I'd suspect Rem is cutting costs by not plugging the barrel before it goes in the park tank...that should be easy to see by shining a bright down the barrel. What also could be happening is a tight chamber by design, or a reamer that's a little worn.

Shotgun chamber hone, $33.99 The right tool for the job. A few passes will give you a nice EVEN finish in the chamber.

1. I stand corrected on the possibility of parking the chamber and/or a dull reamer making the chamber smaller than it should be.

Aippi was kind enough to PM me that the issue is caused by Rem's barrel finish affecting the smoothness of the chamber.

2. I'd still stand by steel wool on either a dowel or a 12ga brush with oil as a lubricant

3. IF you use the chamber hone, BE SURE to use the oil recommended by the hone manufacturer.

4. IF you are NOT experienced in honing (e.g., you've never honed a barrel, an engine cylinder, brake cylinder, etc.) TAKE THE GUN TO SOMEONE who is experienced. A bad hone job can ruin not only the hone, but the barrel.

eta you'll see the correct honing oil at the end of the midway page link

That actually doesn't seem too difficult. Haha thanks. It would be worth it to me to be able to fix the issue at home rather than have to drive to Granite Bay to get it done by Remington. The worst case scenario is I destroy the barrel. haha

PS: There is an area inside the barrel that is noticeably darker than the area before it and also the bore itself. Am I correct in thinking this is the division between the chamber and bore and thus the place I should not pass with the larger wool brush? Thanks again for all the help guys.

You're not gonna' screw up the barrel w/ a brush and steel wool, it's actually a good way to clean the barrel after 4-5 rounds of skeet.

Once you remove the barrel, you can feel the forward end of the chamber with your finger, it's a definite step from the chamber to the slightly smaller barrel diameter. shine a light down the business end, it'll be perfectly clear.

As hank said, you can't hurt it. I polish my barrel after each range session with the tools I described to you. The bore always looks like a mirror. I shoot the cheap low brass stuff that everyone has issues with to test fire my custom builds before I ship them out. Gotta use that stuff to keep cost down. Never have an extraction issue because I hit the chamber first with my polishing tool.

If this does not correct the issue then a light honing is called for, but I am confident the polishing tool will fix you right up.

Excellent. Looks like I get to make a trip to the hardware store tomorrow. Totally solved my dilemma of not having anything productive to do on my day off.

Polishing doesn't always work because some chambers are under size and need to be opened up. I read one case on a forum where a Rem service center smith had to open up the chamber with a reamer.
