Mossberg 930 Not loading

[AlexB]

I bought a Mossberg 930 a few months ago and everything was fine when I test fired it, but now I am having a problem with it not loading shells from the magazine tube to the chamber after the first shell is ejected.

Does any body have a solution to my problem? Thanks.

You need to be more descriptive about the issue. For starters, is the fired shell (first round) ejecting? If so, is the next round getting released but hanging up before reaching the chamber or is it just staying in the mag tube?

[AlexB]

The first shell ejects but the next one just sits in the magazine tube. I don't think it's a spring problem because I can unload the shells manually.

you can try cleaning and lubing all your parts. sometimes my 11-87 gets really cruddy and does the same as you discribed but after a good cleaning its gtg again.

[AlexB]

I tried cleaning it to no avail. Any other suggestions? Thanks!

Alex, I just sent my 930SPX back for the second time for slightly different reasons. Mine wasn't extracting, when it did sometimes it would release two shells from the magazine. I had broken parts in the gas system.
Does your gun function properly when hand cycling dummy rounds? Is the bolt traveling all the way to the rear (hitting the shell release) I just re-read your post, are you unloading by cycling the rounds through the action? Does it lock back with rounds in the magazine?
If you are unloading the gun by cycling the shells through the action (and it works properly)it means the loads you are using are not pushing the bolt back far enough to hit the release.
In that case it's a lube issue, a gas system issue, an ammo problem or "C" all the above.

[AlexB]

I'll check next time I go shoot it. It doesn't cycle rounds when I do it by hand though.

[MossbergMan]

Alex, send it back. If it's less than 2 years old Mossberg will send you a mailing label. It will cost nothing to send it back It will take a few months to get it back, but at least it should, repeat should work.

why send it back when you dont even know whats wrong with it? first, what kind of ammo are you using?

this gun is one of the best in its class because the piston holes are oversize, allowing all BUT the very lightest loads to be used. like the winchester silver box value box stuff, works bad in this gun. but the federal value box works fine

did you do any disassembly to the firearm? improperly re-assembled piston parts could also cause the gun to malfunction.

and thirdly, it sounds like you test fired it but didnt get to fully break the gun in. remember, this is a semi automatic shotgun! it has more moving parts that need to wear in so that you can get the most of your rifle. this should happen only after a few hundred rounds. infact mine broke in after 2 boxes of cheap slugs, and a value pak of federal.

[AlexB]

I did buy the shotgun used, but I will try to put a few boxes of Federal buckshots or slugs through it when I get a chance. Would this explain it not cycling well when I manually cycle it?

[AlexB]

Well, I disassembled and reassembled the shotgun. The problem is still there. I was able to make some observations though.

1. The bolt locks back even if there is a shell in the magazine tube. This is happening when I cycle the bolt manually. I haven't had the time to head out to the range to test fire it.

2. When the bolt cycles, it seems as if the latch that holds the shells in the magazine tube is not moving at all. This explains why the gun is not loading the next shell, but now a new problem arises: Why is the lever not being actuated when the bolt is cycled?

This is the best I can do without actually shooting the gun. Any more help will be greatly appreciated. Thank you in advance.

Alex,

Do this:
1. Clear the weapon and place the safety on
2. Make sure the bolt is closed (SAFETY ON)
3. Insert 2-3 dummy rounds
4. Now press the bolt release

Does a round eject out the tube and onto the elevator? If not, the shell stop is broken, if it does eject it could be that the shell stop is not getting released by the slide during cycling.

[AlexB]

Just did what you said and a round does come out of the tube. So I guess that means the shell stop is not getting released by the slide.

[SarcoBlaster]

Sounds similar to the problem I'm having. When the mag tube is fully loaded with 7 shells, I can pull on the charging handle all day long and it refuses to release a shell, but doesn't lock back. However, if I only load 6 shells into the mag tube, everything functions fine.

It seems like there is too much pressure on the shell stop when 7 rounds are loaded, but the strange thing is that this issue popped up after I put about 250 rounds through the gun and didn't do it when it was brand new.

SEND IT BACK TO MOSSBERG.... It is broken beyond operator level repair. It will cost nothing to send back. Speak with Joe or Rosa in Service. They are becoming 930 experts.
