Remington 870 weak ejection question.

Just bought an older 870 off a fellow EE. Cycles a little rough and was a bit dirty but was in decent condition and a steal at what i had purchased it for. So i thoroughly cleaned it, took of high spots, installed new non-mim (just because) extractor and relubed. Cycled a little smoother but not as buttery as my Mossy 500 and when shooting i found the shells eject about literally 2-4" inches away or stovepipe if im not really working the action hard!

Is there a quick fix for this like bending the ejection tab or is that a stupid idea? Any other help or insight would be much appreciated as im new to the 870 world and searches on the internet have not helped either!

Thanks for the read,

Jeff
 
Polish your chamber my Marine Magnum ejection was rough when I first bought it, had a few failure to extract, ran my finger along the chamber wall I could feel lines almost like threads.
 
Its a manually operated gun. If the ejection is weak, the solution is more time at the gym.

I have three 870s. All of them unmodified out of the box. Only time I have had issues was using crappy ammo where the soft metal on the case head was letting the extractor tear through the rim. Happened about once per box. Either the round extracted/ejected no problem and landed 6-8 ft away, or extractor tore through and the shell was stuck in the chamber.

I switched to high brass ammo and never had it happen again. I have to rack the slide pretty slow in order to have the case eject only 4" inches.

Polishing the chamber does make it far better than stock on the express. Have not had any problems after unless I really don't do my part.

Not much experience with the 870, but I'm inclined to agree with Cam. If it's still not very smooth, try to figure out why. Did you detail strip the whole gun, lubing the bolt and action bars and whatever else moves?

Was it ejecting the same with the original extractor

I will bet you cost of that extractor that the old one worked just fine, but was replaced without ever having been tried. Read alot about the different MIM non MIM extractors and can't for the life of me understand what the fuss is all about.

Hard extractions I can appreciate with certain ammo, dirty chamber, hot barrel, etc. Weak ejection really only comes down to one thing.
 
I would agree with the "gym statement" 9/10 timea but ejector gets weak and will cause weak ejection and stove pipe giving you the hint to replace it no matter how hard you crank on the pump.

Closing up on 10k fired with my 870 and beside 1 extractor, its the only maintenance I had to do. 25$ for the part and 40$ for install. Not too bad for a gun I paid 300$ in 2004 :p

The shape of the ejector spring can often cause weak ejection. One of my 870's (Express) displayed weak ejection compared to my Wingmasters. Comparing ejector springs, the Express spring sat proud of receiver upstream of the ejection lip. This caused the case to get pushed out prematurely, not allowing it to get a good bump from the lip. OK - I'm having a MAM (Middle-Age-Moment), as I cant remember how I remedied it...
 
Bending the ejector will not help. I tried to bend mine a little and it did not make any difference. The OP's complaint is of weak ejection so all the advice about helping with difficult extraction, although good, will not help ejection. Mac's suggestion of re installing the original MIM extractor and trying it may uncover the problem. The new machined extractor my be too sharp and is holding the cartridge rim just a little too long and strong.

For me besides different material they are different profiles and the old style will grab a lot better and sometimes cause issues in newer guns( later than 86) . Weak ejection is not all about strength of pump in some cases

The parts shown are extractors, not ejectors. Extractors don't have much to do with ejection. In fact, after playing with my 870 and a spent shell, I imagine a stronger extractor spring will reduce ejection, not enhance it.

The ejector mounts to the inside of the receiver, and is a solid stop against which the rim of the case is slammed during rearward movement of the action. The faster the action moves to the rear, the harder the shell hits the ejector, the further the shell flies out.

With a 2-3/4 fired shell, I can draw the action back slowly enough that before the shell rim hits the ejector, it is completely clear of the chamber. It does not fall out, but is held firmly against the bolt face by the extractor. A weaker extractor would let go of the case more readily, but that is more a function of the extractor spring than the extractor itself.
 
Wow you guys are amazing with all your information and experience!
Ok, the old extractor was doing the same thing so i opted for the non-mim. I have stripped everything down and polished then lubed many times. It is a Remington express and i am 5'11 235lbs and can rack the slide pretty dang well lol. I just keep scratching my head, even with high brass slugs it just kinda fall out beside me.
 
My 16 gauge express ejects 100% reliably BUT it only dribbles the empties out a few inches from the ejection port. Most empties land at my feet but it has never jammed or failed to feed or eject. I guess if it works it works.

I'm not sure if you are serious or joking. Remove it and see how you get along or try different types and see what difference they make in ejection
You are trying to educate a guy with your version that that has owned, repaired and shot wingmasters since 1965 when I bought my first one new and still own it. I still remember for a few more years I hope what the parts do and how they interact with each other. :) Thank you
I have zero issues of ejection on all 23 or 24 of my 870's so must do something right and even I think have three express in that batch like you do but mine are 410,28 ga and 16ga express rest are all wingmasters

Ok if it did it originally with the fitted extractor also but the gun is not a wingmaster is IT or have a wingmaster barrel
If not polish the chamber first. Lots of posts here how to do that. Then if that doesn't solve it

Try a slight spring bend. Break down your gun and remove the trigger mechanism so you have access to the spring from underneath the receiver. Use a needle nose plier and grasp the wire where it bends and is perpendicular to the length of the gun. Simply rotate the needle nose plier forward to make the bend in the spring more prominent Just slightly. Don't go too far and break the spring, but with slow, controlled force and then see if it made a difference.
Cheers
