    This is my first post so if I'm in the wrong place tell me I bought a brand new mossberg 590 mariner from bass pro and lubed it up and I took it out with some game and some buck shot neither will cycle reliably each shot will lock up my gun to where I have to hit the butt of the gun against a tree to eject the shell and and all help is appreciated. Sorry about spelling this a last minute post before I go to work.

    Check to make sure your scope base screws are not screwed too far in and hitting the bolt.

    Also and I forgot to mention you should check the chamber to see if there is anything there out of place, a large burr, rough chamber, hardened dried lube.You say you tried it with 2 different weights and types of ammo so that should rule out an ammo problem.

    You lubed it, but did you actually clean the chamber and bore before using it?

    Guns are usually coated with a factory preservative to prevent rust before being sold.
    It's necessary to clean that coating off and replace it with a standard lubricant of your choice.

    If you fail to clean the chamber of the coating, it can turn sticky when fired and cause shell cases to stick.

    This is a known problem with the Remington 870 Express and cheap bulk pack ammo as sold by Walmart.
    It can happen with other brands.

    Get a shotgun rod, solvent, and brush and give the chamber and bore a good cleaning.
    Field strip the gun as explained in the owners manual, wipe everything down and apply your favorite lube.

    Possibly this will "cure" the problem.

    Step one, do not bang the butt stock against a tree. Really bad things can happen, not to mention damaging the butt stock.

    Elsewise, mention has been made to the screws and cleaning. But, it is possible to over lube. Might clean it again and be more sparing with lubrication. More isn't always better.

    Some brands of inexpensive shotgun shells are prone to sticking in the chamber. I would suggest trying other brands of shells as well

    Clean the crap out of it. Mossbergs have all sorts of grease, gunk, and metal shavings in them from the factory.

    I cleaned it today so ill take it out tomorrow and try it. I was using some federal 00 buck and it would cycle every other shell but it wont cycle the cheap Walmart ammo which is all I can really afford.

    I've found the cheap Wallmart ammo to be a disappointment over the years for just this case. I've even had my chamber honed and still the Wallmart ammo doesn't work well. Many brands should run fine. Estate typically works well as does the federal top gun birdshot.

    If "game and buckshot" shells won't cycle reliably, I would look for a burr somewhere.......a 590 is as reliable (usually) as death and taxes......

    Now that you have scrubbed out the chamber you may find things working better.

    The suggestion to look for burrs and rough spots is also good.

    On this or any pump gun, slam it open, slam it shut. Working it gently invites a short cycle jam, but you will not break it by working it vigorously. The action will smooth out a bit with some use.

    Keep us advised! Once everything is sorted out you should see a reliability rate of right around 100%. Mossbergs are fantastic that way.

    Bulk federals have been great in mine but not the Winchester universals which are universally crap. While you're checking things out chuck a bore brush in a drill, wrap some fine steel wool around it and polish the chamber. May help.

    Just pray you don't have to send it to Mossberg. I bought a new 935 with a defective barrel. They've had it three months now. Multiple phone calls, 17 emails and they still can't tell me when I'm getting it back. Oh, and they can't get it back to me in the original configuration either because they can't "find" a 22" barrel so they are going to put a 24" on there.

    This is my first Mossberg and I had heard bad things about their customer service but I'm amazed how bad it is.

    Good luck with yours.

    Have recently found some bad lots of bulk 12 gauge where the brass separates from the hull and leaves part of the plastic in the barrel just forward of the chamber. Mossberg pumps typically cycle anything.

    Funny, never heard anything about Mossberg customer service 'cause I never knew anyone that needed them.

    So how is the shotgun working?

    For what it's worth, I have had to use Mossberg customer service. For the most part it's been pretty good for bits that shake off during use over time (I use more locktite now). I did have to send one shotgun back in as shells kept popping out of the mag tube under recoil. The parts they sent me didn't seem to help. Was a quick turn by them and it was fixed. They also had changed out the trigger group (plastic one) that resulted in another problem. even after three plastic trigger units from Mossberg I couldn't get it to run properly without getting 1 ot 2 light primer strikes per box of 25. There is a cross pin in back that holds a spring. As best I can tell, some part during a manufacturing run must have been made out of spec (several calls to get several trigger groups to Mossberg and my explaining what I think was the issue didn't help matters) that resulted in the pin wiggling part way out and the spring in trigger group,wasn't under proper tension or alignment. Finally I resorted to buying the all metal trigger group from Brownells and the problem went away. I was annoyed that Missberg wouldn't give me an all metal trigger group for the plastic one. Such is life. Still love my Mossbergs.

    I do believe as a rule Mossbergs are reliable so their Customer Service is seldom needed. If it is needed though you can be in for a bumpy ride. My one experience with them was less than satisfactory.

    After thorough cleaning and lube I would run some Estate, Rio, etc through it and if the gun still had issues would send in to Mossberg and hope for the best.

    I agree about the Mossberg shotguns. I own two and they've never failed to fire, eject, or perform. The two I own are as solid as you can get. In my opinion they are the AK-47 of shotguns.

    My Mosberg 590 Shockwave did this, and after reading about causes, it turned out to be the extracter screw ,the big flathead screw on the left inside of the receiver, just adjust it so that the action will move freely( loosen to allow to move freely) and leave it there, there could be other reasons for this happening, but check this also, my gun works great now...

    Stay away from the Winchester bulk packs at Wal-Mart. I've had sore luck with it in my guns, it has a well known sticking problem and I keep my chambers clean. I've had good luck with Federal bulk pack rounds, they have treated me much better, and even run great in my Remington 1100 which surprises some people.

    I think that the original Rem Wingmasters are the steel AK-47 of shotguns. I have owned many. They just run all of the time, without a hitch.

    Before my Dad died he tried to pass on his Mossberg 500 to me and I declined, and he was sorely disappointed in me. Probably because he was jealous of my 870's long ago. I used to try to get him out to the skeet range to shoot with me with his Mossberg, but always refused for some reason.

    I am not bad-mouthing Mossbergs but they are not, IMO, anywhere near the same as an 870.
