Hello,

I was at a sporting clay competition this weekend and unfortunately found out that my rem 870 supermag has decided to not eject the shell after firing of certain ammo. It seemed to only happen to Winchester super target shells, I would have to put the gun against me and pull very hard to open the action. This happened consistently with these shells but not other more expensive shells. I heard rumors that this is due to the fact that it is a low brass shell and expands in the chamber and gets stuck, because they are cheap.

Now is this an issue that I should contact Remington and use my warranty and get the gun serviced?But I have also heard that with 870's after wearing in the gun and using it more this problem will go away?

Any experience or suggestions? Thanks...
 
Ok, so if I avoid "no brass" shells I should be fine? I guess if this is a common issue no need to send to Remington?

Sucks that I have to avoid using the cheap shells lol
 
I have read on different forums in the past couple of years that the cheap Winchester shells can cause problems. Is this the only shells that cause a problem. If so then I don't think there is much point in contacting Remington . Many times you will read of certain guns that don't work well with a certain type of ammo. If you have the problem with other brands, then yes there is a problem.

I cannot guarantee anything, but that would be my first guess if you are shooting those white box winny. Try some AA or even remmy dove loads and see if it improves.

If not, then maybe try polishing the chamber for the 870, lots of info online about it.
 
Polish the chamber... the issue will disappear!

The problem is the cheapy shells have an aluminum base... it expands slightly under firing, and can get stuck on small burs/scratches in the chamber. Polish it, and you'll be smooth cycling forever!
 
I read awhile back on another forum that often, with the Remington, the problem was caused in the receiver area, right in front of the chamber. You should see tooling marks there though if that is the problem. If you see any machining marks or ridges in this area, polish that as well.
 
Okay, thanks

I will definitely try polishing because I have a bunch of shells and don't want them to go to waste. I may be back to ask some questions about doing that...
 
Are they aluminum or steel bases. (if a magnet sticks steel) Steel is not as elastic as brass. Expand on shooting but don't return as much after thus stick more to the chamber. just my .02
 
I had an 870 super mag that jammed as the OP described. It's a common problem. I actually broke the forearm trying to open the action. It was the first and last Remington product I ever bought.

Agreed. Add some fine steel wool to a rod, then use an electric drill motor. Add a bit of oil for lube. Just the chamber, not the barrel.

This worked for me to correct the problem. I used a 12 ga brass brush wrapped with steel wool.
 
Your gun is manufactured by Remington and covered warranty. Gravel Agencies in Quebec City is the sales agency for Remington in Canada, as well operate a warranty depot. Your barrel, when removed from the frame and looking into the chamber should show some burring at 10 O'clock and/or 2 O'clock. They will correct this, test fire it and return it to you. This problem occurs in a lot of 870s and is easy for them to correct, suprised they haven't address this at the factory. Good shells will probably work fine but give them a chance to get it working with the cheap shells. I've seen a lot of guns work well with Remington or Federal, seems Winchester is more problematic.

Buff/polish the chamber with a dowel and emory paper.
Cut a slot in the end of dowel and them insert emory paper into the slot.
With an electric drill polish the chamber and Bobs your Uncle.
You will spend more time assembling the material than the actually polish/buff.
It is common with the express and non wingmaster guns and a common fix.
But, with me not reading the three pages of comments, I hope this one is not in vain.

The Winchester Universal hulls do not have an aluminum base. They are a steel base with a silver plating. Check it out with a magnet.
 
I have the same problem with cheap Federal stuff. I have a case of the cheap remington stuff, but I've yet to fire it. With my Savage 350 I have a fail to extract one out of twenty five times. I'm glad I read this as there is a slight bur on a keyway at the rear of the barrel that grabs at cleaning tools. I suspect that may also cause the jam problem.

This man is dead on, rough, poorly finished chamber is the #1 cause of the issue you're describing, unfortunately common in Remingtons including one of mine.
