Hi,

I just recently purchased the Mossberg 930 HS and was able to go to the range today and test it out.

Just wanted to report back that I'm fairly satisfied with its performance. I was mainly firing #7 Birdshot but also put a few slugs thru it.

The kick from the birdshot was pretty minimal, but the slug definitely packed a punch!

I did run into a one issue I'm hoping for some help with. A few times, after loading 2-4shells into the magazine, when I racked the slide the shell didn't get elevated into the chamber, sometimes nothing at all happened, and other times the shell only moved onto the elevator, with the 2nd shell behind it also sitting partially on the elevator. To fix it, I had to push the 2nd shell back into the magazine, and then closing the action then loaded the gun.

What would cause this? Is this a gun problem, or more likely an ammo issue?

Thanks
 
What slide were you racking on a Mossberg 930?

Was the issue with slugs?

My 930 wouldn't chamber a few kinds of slugs as reliably as others. I would push the button to close the action and it would drop the slug onto the carrier, then I would have to push it again to have it chamber.

I believe it has something to do with the slightly larger brass diameter of some slugs.

Thanks for the reply. The issue was with the #7 birdshot I was using. I only fired 3 slugs, the rest was birdshot.

I'm hoping it's the ammo and not the gun being an issue.

Thanks
 
Check your gas piston. Seriously. Same happened to my friend. Accidentally shot the wrong slug through a non rifled barrel and wrecked the two silica carbide rings on the gas piston.

Not saying you did this but worth the 30second check.

Thanks for the info. Forgive my newbie question but how would I do this and what exactly would I look for?

I only shot 3 rifled slugs(federal ammo 2 3/4) thru the Mossberg 930. From what I read my understanding was that this is fine. Can you confirm?

Also, I'm trying to remember if this issue happened prior to shooting the first slug and I think it did.

Thanks
 
Not shooting rifled slugs per say through the non rifled barrel. Doing this we believe to have wrecked the gas piston on my friends 930 so he had to get a new one.

We found this out as it would not cycle the target load right after so we took it apart. After you slide the forend off and remove the barrel its the little black cup assembly above the spacer tube. When removing the barrel it may stay attached to the barrel or it may stay attached to the mag tube. He bought the 930 combo with two barrels but it never came with two gas pistons.

See below for some shots of the gas piston and a generic disassembly.

Again I am not saying you guys did this but it only takes 30 seconds to check. Lesson well learned for my newbie friend. Never trust what someone at Cabelas picks out for you to shoot through your gun but also read the labels :D and use the appropriate barrel for the load you are shooting LOL!.

This was our experience with the 930. We are assuming the gas piston rings broke from shooting load through a barrel not designed for it. Anyways a new gas piston is in and works great now for any shell as long as the right barrel is in place. 100+ target loads through it, 00buck, bird shot, and 10 or so very powerful rifled sabot slugs though the new piston and running/ cycling great.

"Fully rifled barrels deliver best accuracy with sabot style slugs. “Rifled” slugs and
shotshells are not recommended for use in rifled barrels."

From the 930 Manual.
 
Not sure how Mobgma's situation happened; can't fathom how using the wrong slugs would do anything to the gas system (But I'll be the first to admit, I know pretty much nothing about how it works).

Regardless. I do know this (from personal experience)

For best results
smooth bore = Rifled slug or buckshot
rifled barrel = Sabot slug

My 930 (deer combo); didn't want to shoot the cheap Walmart value pack bird shot at first. Wouldn't eject right. I then sighted in my deer barrel with 3" slugs (20 of them) and it no longer has any problems with any ammo (that I have laying around)

As I said we believe that is what happened coupled with the fact that is also what Cabelas told us when we brought it in. I am no expert on shotguns either, just sharing my experience. Whether that is what did it or not we will never know for sure.
 
When the round is released from the magazine on the rearward movement of the carrier it needs to hit the elevator release to be chambered on the forward action. If you put your finger( while holding the bolt handle or your finger will get jammed!!) on the inside you'll feel the mechanism. A round having trouble coming out if the magazine without force will not engage it.
The action not coming all the way rearward( insufficient gas) or round ceasing in magazine( jammed follower or weak spring) will do this.
New guns need to be broken in( especially this model). The most common mistake guys have with the 930 is that the pusher assembly has the spring on the wrong side.
Semis need to be babied and cleaned. If your friends gun is running on bird shot but not slugs he could be" limp wristing" it, meaning he's not holding the gun firm as anticipating recoil(maybe).

ook, sooooo what we are saying hear is that the wrong wround through a smoothbore damaged a part of the gas system? does a rifled barrel have a different sized gas port? runing sabo slugs through a smoothbore is what dicked the piston? or was it runing rifled slugs ? Im somewhat confused, and find it hard to accept. Im gusing it was a falty part and the experienced gunsmith at cabela's was wrong.
 
I am not saying this damaged anything. I said if you can check it than do it as only takes about 30 seconds. It is most likely not a problem though.

I would agree that the gun likely has to be broken in first and could be why you are having cycling issues. I would follow hat Jamiejaf said above.

I really appreciate all the feedback on this, this forum community has been really nice and supportive! :rockOn:

Based on Mobgma's info above, this would indicate the 930 CAN handle rifled slugs and I at least didn't goof by shooting the wrong ammo in it. I will still check on the gas system though.

Jamiejaf's info regarding needing to be broken could be accurate too, as this 930 is brand new and it was the first time it had been fired. Maybe there are just some issues to work thru. I only fired about 50 rounds thru it at the range, including 3 slugs.

Thanks
 
I've included a pic using snap caps of what I had happen to me a few times at the range.

You'll see that 2 shells are ejected from the magazine onto the elevator, but that of course neither get moved up into the chamber.

What you need to do in order to fix it, is push that 2nd round back into the magazine, which will then cause the action to close and move the 1st shell up into the chamber.

Clear as mud right? Any other ideas?

Again to give more info, my 930 is brand new, the ammo was #7 birdshot. I've heard many suggestions from possible gas cylinder issue, gun needs to be broken in, to its an issue with the ammo.

My main concern is with the gun, I can always buy other ammo.

Thanks!
