    Hey all.

    So My new Mossberg 500 Thunder Ranch came in from bud's yesterday and I eagerly picked it up. Being my first firearm I have been reading the manual and practicing loading and unloading shells. I hit a snag almost immediately.

    The style of unloading preferred in the manual (supposedly) is the this:
    - Flip the gun upside down, depress the cartridge stop and the shell will pop out do this one at a time until unloaded.

    This is demonstrated in this video:

    However, my Thunder Ranch 500 will not unload like this. On the elevator there is a large "notch" of some sort that sticks out.

    [​IMG]

    When I depress the cartridge stop the shell only pops out about an 1/8 of an inch, and the shell rim hits that notch on the elevator, preventing me from unloading the magazine.

    It seems insane that on a "home defense" special model of the mossberg 500, they would use a part on purpose that prevents the safest way to unload the gun.

    I'm really frustrated here. Is this notch thing normal? Please help me not be upset at my first gun purchase :(

    Well after playing with it a bit, I can pull forward on the shell to slide it "around" that notch to unload the shell, but it takes a bunch of pressure and sometimes it doesn't work still. In addition, just loading the shells into the magazine takes more pressure that it seems like it should, because that notch is so pronounced. The shell's rim is actually scraping that notch and then clicking down over it before it even goes fully into the tube. It scrapes the notch hard enough that after only loading about 10 shells total into the tube the black finish on the center of the notch is now silver because of the scraping of the shell's rim...

    Is this something to be concerned about?

    in the video above the shells just pop out with no problem whatsoever. I need to pull the shell out with a tug over the notch and that doesn't seem like it should be necessary. And will having to scrape past this notch while loading potentially damage the shell at all making it unsafe to fire? I just don't know, but I'm really upset that I might need to ship the gun to mossberg before even firing a shot. Putting a REALLY sour taste in my mouth.

    It may be related to the "newness" of the gun. Shoot a few boxes through it. Cycle it dry a few hundred times and it should smooth out. I am not a big Mossberg fan, but they do seem to work.

    Hmm... how would dry cycling change the pronounced-ness of that notch on the elevator? Like i said the shell rims are scraping that thing every time. And no matter how much force I put on the evlevator, it won't push down another millimeter to make to it work like it appears it should.

    I appreciate the reply for sure, but I'm not sure how putting rounds or dry cycling will do anything to a metal piece that refuses to budge :(

    Do you have the slide in the "closed" position?

    Yes, or else I wouldn't be able to access the the magazine tube at all because the elevator would be down blocking the tube?

    If you are referring to the picture, no I have it open so I could get a good picture of the notch I was referring to.

    No, it was hard to tell from the photo what was hanging up the shell, with the bolt closed the elevator should rest against the top of the receiver. Did it lay flat when you installed the barrel?

    Here are two pictures that show exactly what I'm talking about.

    The first shows the shell being fully in the tube and held in by the "cartridge stop":

    [​IMG]



    The second shows what happens to the shell when I push in the cartridge stop bar. The shell ejects partially and gets stuck on the elevator arm. This picture also shows the scratching that this occurring in multiple places on the elevator because it is raised so high the shell rim scratches it hard on the way into the magazine tube (the white lines on the elevator):

    Hopefully these pictures help explain what is happening.

    I would try taking off the barrel, giving everything a good oiling then reinstall the barrel, making sure all the cuts and notches line up. My Mossberg's action was "gritty" as hell out of the box. Check out the vid below, this gun appears to have the same type of elevator but the shell pops right out without a lot of force.

    Interesting. Yes his elevator looks similar, and his did catch ever so slightly one time. The next two shells he unloads in that fashion don't catch. The pictures I posted show that there is a considerable part of the shell that catches in the elevator.

    This mossberg came fully assembled in the box when it arrived at my FFL. I'll have the read up on how to remove the barrel, what type of oil I'm supposed to buy, how to apply it and then how to reinstall the barrel.

    I just didn't want to bother with all of that if the elevator is defective and will need to be returned to mossberg. If that needs to happen the sooner the better. I have read stories online of people waiting 2-3 months before receiving their gun back from mossberg service...

    Mossberg barrel comes off real easy, unscrew the nut on the end of the mag tube and slide it out.

    Remoil or Mobil 1 for that matter works fine. Either break the action down and wipe each part down or use your finger to spread a few drop around and cycle the action. If 2-3 months is the norm, an elevator assembly is a $30 "drop in" part at Midway or Brownells.

    I think you are worrying over nothing. As long as the shot exits the barrel like it should when you pull the trigger and reloads when you cycle the action, I wouldn't worry about having to wiggle a shell to unload the magazine from the bottom. I can unload my 870 in similar fashion, but I just run them thru the action. If you are worried about running them thru the chamber (I wouldn't worry one iota) just don't close the action all the way and the interrupter will not let the hammer fall anyway.

    Well I think that since the gun is supposed to allow for unloading this way (and it is the preferred method according to the manual) that it should actually work out of the box. $400 is a lot of money to me and my wife, and if I'm buying something new than it should work as intended and as the manual says it should.

    The bigger immediate concern is that the elevator is being heavily scraped by the shell as it goes in. I don't know enough about shotgun shells to know if putting sideways pressure on the shell by having the elevator push on the side of the shell while it loads into the magazine is dangerous. All I know is that it isn't supposed to happen so it shouldn't be.

    I appreciate the link to the elevator "drop in part", although it is out of stock. But there's no reason to believe it isn't a different part in the gun preventing the elevator from going all the way up and out of the way. And I don't have $30 to waste without knowing.

    I suppose I could bring it to the FFL I picked it up from and see if they would be willing to give it a look over, but who knows if they will charge me...

    Why not just pull the slide back let the round fall onto the feed tray tip the shotgun over & dump it out & repeat ??????????????

    I have owned several M500's and I had the following problem w/ everyone of them. When the forearm was pulled back, a shell from the magazine would occasionally, not everytime, but often enough to make it frustrating and aggravating, drop out onto the ground instead of going into the chamber. I believe the design of the action is inherent to this malfunction because the shell elevator does not always come down fast enough to catch the next shell. When I wanted a rugged inexpensive pump shotgun for duck hunting, I got a Benelli Nova. I have never had a problem since.

    Because I'm not supposed to have to do that. I bought it new, it should be fully functional in compliance with the owner's manual. Maybe that makes me weird, but I thnik things should function as they are supposed to when I spend my hard earned money on them.

    Prefered method per manual?
    Or is it prefered method in manual put forth by legal representation?

    That way if you do it differently, and something happens, you can't sue them.............. ;)

    Really, get the round on the carrier and don't chamber it, just flip the gun to the side and dump it out like others suggest.

    Maybe the ammo you have is a little larger OD and it doesn't allow for enough wiggle to get past the tab with moderate thumb pressure.

    I dunno, never unload my shotguns that way, and gave up on Mossberg a long time ago.

    I understand and its definitely another way to unload it. I would love it if anyone can also speak to my concern about the shell rims scraping the elevator as they are fed into the magazine. It puts pressure on the side of the shell and I am nervous that it can be a safety concern. Nothing should be scarping anything. That is the reason I am more upset, because it appears something isn't laying correctly inside the gun possibly preventing the elevator from laying flat.

    If its a safety issue to have that pressure put on the shell while loading it needs to be addressed and is more of a problem than the unloading technique.
