*Partial update below: post #8*

Hey guys, Just got a used 18.5"bbl 590A1.

First day at the range today, and it didn't go to hot.



When I pump it, I have to really slam it back to get it to eject the fired shell(or un-fired as well).

*Photos to come. *

I'm not short stroking it, or just being too ginger. If I hesitate the slightest bit, it will not eject, and another shell will jam in under it. That isn't 100% either, sometimes, even when racked back hard it will still jam.

Also, I had several light primer strikes that resulted in a FTF. (never seen that happen before on a shotgun)

I guess I assumed these guns were absolute tanks.. they do feel study but I've got the two problems above, and the tube spring feels really weak too.

So... where to start?

As far back as it will pump, before stopping and not ejecting.

right about where it gets stuck,

Darn, out of focus, but i think the position is still visable

Rule #1 with a pump shotgun is to rack it like you have a pair of cojones--ALWAYS and EVERY SHOT.

I recommend to all Mossberg owners with 20" mag tubes that they invest $8 in a Wolf Magazine Spring for their guns. It makes a big difference and yes the factoy spring is weak and yes they shouldn't make it that way. But they do and a new factory spring will be just like the one you have now. So go on gunsprings.com and spring for $8 and you will smile when you install it. I promise.

Lastly, new Mossbergs (and Remington Express models for that matter) all require some shooting to break in and smooth out the action. I highly recommend you take my first bit of advice above in terms of how hard you cycle the action but especially for the first 200 rounds or so and you will probably be amazed at how much the gun slicks up....

Not saying you don't have a problem with your ejector. If you do its an easy fix with a new part from Mossberg and a screwdriver (unlike an 870 ejector which is riveted into the side of the receiver). But before you come to that conclusion you need to understand a pump shotgun needs to be cycled with some authority.

In terms of light primer strikes...I've had bad boxes of ammo before that had primer problems and wouldn't fire. Might not be the gun. Take the gun apart and diassemble the bolt to make sure there isn't any debris in the firing pin channel. There are Youtube vidoes how to do this. I'd look at the firing pin channel first. Then look at the trigger housing to make sure nothing is interfering with the hammer fall. Finally, if you've only tried on box of shells try a different brand. There is tremendous variation in shotshell quality.

What shells are you using? And are they all from the same box?

Thanks guys.

I shot about 100-150 rounds, Remington and Winchester from wallyworld, a box of slugs, some reloaded shells from a friend, and a few others. Probably 5 or 6 different types total. All had issues. I've got a maverick 88, and a 500ab, so fairly used to mossbergs and the force I have to exert just can't be good for the gun.

This gun was made in 2002. should have more than enough rounds though it to break it in. I'm the 3rd owner, at least.

I'll definitely give the spring a try. When I cleaned the gun, I found that the spring had some rusting going on and I don't want that spreading. the ejector just looks like its been beat up pretty good..

Do you know a good place to purchase parts? I've never actually bought any shotgun parts before.

I would say F the BS and give Mossberg a call on this one. Sounds like something isn't right. You shouldn't have to rack a shotgun slide like you're trying to rape it for it to work correctly.

Just my opinion.

Interesting about the Wolf spring...the stock spring on my 20" 835 has seemed a little weak.

Tempting, but I want to see if I can resolve it first, without having to ship it out and wait for it to be returned.

Thanks! that doesn't seem bad at all.

I detail stripped it, and cleaned it out really well. (didn't take apart the firing pin, yet though), and its ejecting some of the spent shells I have a little better than before. I really should have cleaned it before the range trip but it looked pretty clean.

*Update*

Tried maverick 88 ejector in 590.

Didn't help, actually made it worse in a way.

The less worn ejector now cuts the shells! first shell ejected ok, second got stuck took 3-4 re-racks then it just cut through it, and i had to pop it out by hand.

Bigbird,

Is this the spring you recommend?

I've owned several 590's and 590A1's, and presently own several. I've never had a spring problem, nor a break-in problem. Certainly the action gets smoother with use, as is the case with any pump shotgun. If ejection problems are occurring, that's mechanical, not a "break-in" issue.

One shouldn't need to rack the weapon hard to eject an empty or loaded shell.

 

[geofri]

Oddly, the problem seems to me clearing up.

Not sure why. Haven'e been able to get to the range, but cycling lots of empty shells, and now only 1 out of every 5-10 seem to get hung up.


Waiting for a call back from a mossberg tech to offer an opinion.

No,

If your gun is a 6 shot model you need SKU 17901. On the Wolff website do a model search for Mossberg Shotguns and you will see it under the model 500 springs and the 590A1 is also listed with that spring.

Ah! Thanks.

Thought a one size fits all was strange..

Ah! Thanks.

The Wolff spring is made extra long to be cut to fit. Count the coils on your stock spring, and cut the new one to have the same number of coils, regardless of it's length.
