I have a 930 that I am happy with in every aspect except one. I am trying to figure out why when I only have a couple of shells in the tube I don't have to pull the charging handle very hard to load one in the chamber. With five in the tube I can load a shell every time but only if I pull the charging handle back super hard and fast otherwise it won't pull anything out of the tube. It's doesn't have many rounds down it yet so I am assuming it just needs some working in?
Mossberg 930 guys please help...

The first problem is because it is a Mossberg...and I'm serious about that! The other problem is the shell stop. With five shell in the tube, the compressed mag spring is causing the shells to exert higher pressure against the shell stop and preventing it from sliding off the shotshell rim and allowing the shell to release. If you flip the shotgun upside down and pull the charging handle back slowly you'll see what I mean. Many Mossberg pump guns have the same issue. A little filing is all that is needed to remedy the problem. File the shell stop down a little bit, then try it...repeat until the gun cycles everytime.
To the OP, how many rounds have you fired through it so far?
VLT79's explanation is sound, could be the mag spring is abit too long.
Though I've yet to experience a single issue with my 930 since I broke it in with magnum slugs.

I appreciate your info. In fact I was already looking at the shell stop before my post and sanded it a bit. Wasn't brave enough to go for the file yet but I feel more confident that's it now.
As far as saying it being a Mossberg is the first problem, you need to explain that? The only reason I have two 590A1s and one 930 is from seeing what doesn't jam up for people at matches and asking top shooters their advice. Now the 590s I have put through the ringer. I would trust a 590 over any other shotgun. In fact it's not just an Internet myth that the 590A1 was the only shotgun that passed the military's torture test of 10,000 rounds. After 3,000 rounds of magnum buckshot loads it was the only shotgun that had every part fully functioning.
The 930 although I haven't put through the ringer myself I chose due to it being one of the most reliable semis at 3-guns and IPSC shotgun matches. Benellis and Winchester SX3s were up there as well. If price wasn't an option I would go Benelli or Winchester but the 1100s are garbage for the most part at matches. They may be good for hunting but when you push them to fire 10-20 rounds as fast as you can load and shoot them they are horrible.
Not many at all. That will change soon. Your experience with the 930 is similar to most I have spoken with.
The U.S. military torture test/trials can be taken with a grain of salt. A platform's overall reliability has to be averaged over a much larger number of firearms than what the U.S military used to come to the conclusion. A little known fact about the U.S choice of the 590-A1 over some others was nothing more than price. In my experience Mossberg shotguns tend to have more initial cycling problems than most other brands. Like I said earlier the shellstops (being too long) also plague many of the pump guns, mostly the 500 and Maverick models. The 930 semi-autos don't have a very long lifespan. They were designed for the average hunter than fires an average amount of ammo, meaning less than 200rds a year. Most hunters/shooters couldn't keep track of round count if their life depended on it and grossly over-estimate the actual number...200rds becomes 1500rds. The 930's reliabilty disappears by 5000rds and many examples I've seen never made it to 3500rds. We aren't talking full-power loads here either, these were trap and sporting clays loads.
Interesting. I can't really argue about the 930 as all the reliable ones I have witnessed at matches may be before the 3000-5000 round mark. The 590A1's on the other hand are just tanks. I have 5,000 through one of mine easily. Probably more. It hasn't had a hiccup. I will use my 930 until it fails me. Do you have a recommendation for a tough long lasting reliable semi?
Benellis and Berettas seem to last forever as far as rond count goes, they seem to be the concenus choice in applications where a ridiculous amount of shooting is expected like Argentinian dove hunt rentals and certain gun games.
Anyway, I think Mossberg puts out a good basic product, but they've always had these annoying cheap touches that keep them from being as good as they should be.
I have been doing a lot of shotgun lately. Actually won that last IPSC level 1 in open division a couple of weeks ago. This is the school of thought from every top guy I have talked to and observed. Buy a Mossberg 930 unless price isn't an option then go for an M2/M4 or SX3. I am sure whatever the parts are that supposedly don't last past 3500-5000 rounds can be replaced with better ones regardless.
I have seen only three Hatsans at matches and they all turned from semi into pump due to the need to clear a jam after every round. No joke all three had the same issue. Plus you cannot ghost load them. In my opinion they are a poor choice for matches.
