    I bought a new Mossberg 590 Special Purpose about 3 months ago (my first Mossberg). I've had it to the range two times. It holds 9 - 2 3/4 inch shells. When I fully load the magazine with 8 shells and rack the slide, the first shell out of the magazine falls out of the bottom of the gun. When I rack the slide a second time, the next shell loads into the chamber the way it is supposed to. If I load only 7 shells into the magazine and rack the slide, the first shell loads into the chamber the way its supposed to. Am I doing something wrong or is something wrong with the gun. I want to keep the gun loaded with the chamber empty. For now, I'm keeping 7 in the magazine untill I find out what to do.
    If I'm doing something wrong, please be gentle, I'm more into handguns than shotguns. Thanks

    I forgot to ad

    If I load a shell into the chamber and then load 8 shells into the magazine so the gun is fully loaded with 9 shells, it functions perfectly.

    Well....mine doesn't do that. ;) I think you should call Mossberg and describe your problem in detail to them.

    When you load 8 and try to chamber a shell, does the shell elevator swing down to catch the shell coming out of the mag?

    When I rack the slide, the shell pops out before the elevator swings down. How hard is it to load the 8th shell in your gun? It almost seems like there is too much spring tension when the 8th shell is loaded in the magazine. As soon as the slide starts backward, the shell comes flying out before the elevator has a chance to catch it. I am using 2 3/4 inch shells before anyone asks :rolleyes: The ammo I'm using is the Federal Tactical. I don't have any other ammo on hand to try.

    This happened to me when I first bought my Mossy 500. I discovered that I wasn't always pushing the last shell in far enough for the rim to snap past the cartridge stop. Also, short stroking the action is a common reason for this to happen.

    I had this happen--in a class--with my 500. I sent it to Mossberg and they fixed it under warranty.

    The last round you are putting in the magazine is either not being pushed completely past the cartridge interuptor , or it needs a slight adjustment . It sounds like the first may be the problem.

    Make sure the last round is completely seated into the mag tube, not just past the cartridge stop. Some brands of shells at times can run a little long and this also will creat the problem, as the last round can't be pushed far enough forward to properly lock into the magazine.

    Problem solved

    thanks to all who replied.
    I finally got around to trying different ammo. I had some Remington target loads on hand. I loaded 8 in the mag and they fed perfectly. I then stood the Remingtons side by side with the Federal Tactical buckshot and noticed that the Federal buckshot is about 1/16" longer than the Remington. I compared the Federal Tactical slugs to the buckshot and they also were about 1/16" shorter. I loaded the mag with 4 buckshot and 4 slugs and my gun functions they way it should.
    Being relatively new to shotguns, I thought shotgun shells would be uniformally the same size like handgun ammo. Is it common for there to be such a big difference in the length of the shells between types and brands of ammo?

    Going with your experimentation I will have to say that your original thought about the magazine spring may be on target.
    Clipping no more than two coils off the top of the magazine spring should solve your ammunition feed issue with the Federal shells.

    It should not affect feeding the slightly shorter target shells in any way.
