I have owned an 870 Supermag and right from day one it had ejection problems where empties would stick in the chamber, I have heard this was a common problem. This was fixed under warranty.

Now I have a Norinco HP-9 fitted with an 870 Supermag bbl and I am having the same problem, I highly doubt warranty will help me now as I bought the bbl last year on CGN.

Also today while hunting one of our party also had a supermag with similar problems with certain ammo.

Any idea how I can fix this at home?

I had the same problem with extraction. Seems to be a common problem with the newer supermags. They suffer from bad chamber reams resulting in zero extraction. Your going to have to have the chamber polished. This should fix the problems. Or take the route I did and get a Supernova :D

I can't buy another gun as this is my "spare" for taking kids or lending to buddies.

I once tried running some sandpaper on a dowel in a drill through the chamber, maybe I'll just do it some more until it seems to work.

It does not seem to be an issue with all shells but it is with most especially 3"

STOP! Don't use sand paper. It is way to agressive. Some really fine steel wool on a dowel and a light oil is all you should need. What was this certain ammo that was the problem? lemme guess winchester cheep stuff?
 
How many rounds have you had through it?
What did they do to it under warrantee?

I had the same problem on my 870 XCS Marine Magnum. They would not warrantee it, they just said "run more rounds through it till it wears in" which I did and the problem was solved. I have spoken with lots of people who have had this also on their turkey express and other 870 models.
 
870 extraction woes

Call Dave Henry Gunmakers. (403) 748-3030. He'll fix it up chop chop, and it will only cost you the fair cost of excellent workmanship for a job properly done, plus shipping. Probably better than using sandpaper, or even steel wool on a dowel.
 
I have the same problem on a 870 express with the 18.5 barrel. Works fine with quality ammo tho
 
I had the same problem, only the chamber was much tighter than that. The shells would get completely stuck.

I reamed it out with a brake hone on a hand drill, worked like a charm.
 
If a chamber shows reaming marks to the point that extraction is a problem, the barrel is defective, and should never have left the factory.
This does not seem to be a rare defect in new Remingtons.
It should not be necessary to have a chamber polished on a brand new gun in order to get it to work, nor should it be necessary to shoot the thing until it starts to work.
Should be functional and reliable right out of the box.
 
I have fixed quite a few new guns that came in with the same problem. tiriaq is correct in that they should never have left the factory that way but they do. All of them had rings in the chambers that cause fail to extracts. Honing them cured all the problems.

This is one more example of the Walmart society where all producers of products are trying to make everything as cheap as possible because most people want the very lowest price.
 
My 870 express that I just bought does the same. Its too bad that remington has taken on the Walmart way of looking at guns they put their name on. I have a early sixties 870 that has had tens of thousands of rounds through it and never had a problem thats why I bought a new one. The old one is simply getting tired.

So... is there an easy wway for me to do it at home? the nearest "qualified" smith is a few hours away and will take months to get it done. He did my previous 870 for me but it was under warranty and not in hunting season.

Somone mentioned steel wool on a dowel, I am not sure how I would get steel wool to stay on a dowel. When I tried the sand paper I rolled it up and let it spin loosely in the chamber, I was going to try it again with a finer grit but was warned to stay away from SP on here!

You can use a dowel, but I use a 3/8" piece of brass rod...either will work. Cut a slot in the end lengthwise to insert the end of the sandpaper. Use 180 grit. Wrap the sandpaper around the rod and chuck it in an electric drill. The roll that you make should be snug in the chamber. As the drill rotates the rod at a fast speed, move it in an in and out fashion to polish the chamber. Go all the way up to forcing cone. Do not bring it all the way out while it is spinning or you will have a surprise. Do it for about 30 seconds and look at your progress. After you wipe out the dust, you can see if there are any rings left in your chamber. Good Luck!
 
Quite often there are a few burrs just back of the recess for the rim of the shells on the barrel extension. They prevent the rim of a fired shell from getting past but do not restrict an unfired shell. I remove these burrs with a scraper made from a sharpened 3-corner file. I have encountered dozens of barrels with this problem and invariably this procedure has solved the problem. Quality control has "gone out the window" on the 870's particularly the Express models.
 
I agree.

Same problem with my brand new 870 express. But it gets better. The warranty repair depot in QB denied that they had ever even heard of this problem! They swore that quality control had not suffered in the recent years. Obviously they have not heard of google. http://www.youtube.com/watch?v=eu9LIroAEuw

They promised a 6 week to 3 month return window. I passed on that opportunity:) Bought a new non-MIM extractor, and it helped a bit. But now working on polishing the chamber. The fact is, if I can do it (ability-wise), it's almost a crime that Remington refuses to do it in their factory.

Sad descent into a Walmart company....
 
Steel wool on a dowel... it would take hours to actually polish any roughness away... just shines up the high spots.

Sandpaper is for wood.

If it is rough, 220 grit wet/dry paper on a split dowel for a few passes, then 320 grit...

Cheap ammo accentuates the problem if there is any roughness.
