Remington 870 extraction problems

[JediKnight]

Hey guys my brother just bought and 870 super mag and it won't quit jamming. It always feeds just fine and fires reliably but when it comes time to extract the used shell its jammed up and it takes a couple of minutes or messing with it before it comes free. Its got the 5 round magazine and it seems like we can never get through at least 1 magazine without it happening at least once. Let me know if anyone has any solutions.

thanks

This seems to be pretty common, especially with the Super-Magnums in my experience. I had the exact problem with the same gun several years ago. Since I live within easy driving distance of a Remington service center I just took the gun to them.

All they did was give the chamber a good cleaning and spent a little time polishing the inside of the chamber with steel wool. Worked fine after that. I could have easily done the same thing and saved a trip if I had known.

Was the gun cleaned prior to firing? There's usually preservative all over a new gun, even inside the barrel. Give it a good cleaning, then try again. Still got problems, polish the chamber with steel wool.

Ammo choice also matters. Winchester seems to be a bit sticky.

870 ejector problem

The previous replies about cleaning out the new gun protective coating are right.

I bought a five year old, unfired Wingmaster and didn't think to clean what appeared to be a perfectly clean bore. Unfired means it will have that protective coating which must be removed or it will become hard to remove once the gun has a couple of boxes of shells through it. My gun didn't fail to eject but I couldn't remove that darkish film just past the chamber.

J.D. McGuire (AIP Tactical) recommended on another forum to use an "0" or "00" steel wool wrapped around the end of a dowel (I think mine was a 5/16" diameter x 30") and taped tightly to the the dowel. The dowel is then run at a medium speed through the bore with a drill. You probably have a RemChoke screwed in. It may take several minutes and the barrel will get warm to the touch. After the gunk is gone you'll notice a very nicely polished bore.



If the choke is Full or Modified, be careful as the drill and steel wool may unscrew the choke depending on the direction (Go counterclockwise from the chamber end of your barrel.) Keep a choke screwed into the barrel and don't run the steel wool over the choke treads of the barrel if the choke isn't in place. I shoot mostly the Improved or a skeet choke which I clean separately after I'm done cleaning the barrel with the steelwool and dowel. Follow by coating the barrel with very light coat of gun oil. After 40 years I've switched to a couple of shots of RemOil spray and running two or three clean patches through to get thin coating and to remove any excess.

The ejection problem with a new 870 is curable with this easy method. Evidently it is more common with the 870 Express

Clean the chamber, polish with #000 steel wool, replace the extractors because they are damaged from sliding off the rim.
Lightly oil chamber, let sit for 10 minutes, wipe dry, shoot.

Are you using low brass ammunition? I have observed that the low brass ammunition, typically the less costly target/range stuff, tends to rip rather than extract. Cleaning/lubing/polishing can help, but take a look at higher brass ammunition, too.
