First off, just want to introduce myself. My name is Josh, I was raised in Alaska but currently live in Washington state (hope to move back this winter). I have been around all sorts of guns all my life, but just to shoot. I never had the initiative to learn much about them though! But better late than never, right? haha.

On to my problem/questions.

I have recently been given my Grand Fathers Remington 1100 shotgun semi auto magnum for 3 inch shells. This was probably the number one gun I shot when I was in Alaska (was always a favorite). And it had ZERO problems what so ever. I fly it back down from my last trip to Alaska, and it won't eject the shells. My friend had a large amount of Winchester/Federal, 2 and 3/4 inch shells and that's what I have been using (I'm about to buy some Remington). Anyways I was talking to some gun folks around here and looking online and this is what I came up with.

The reason my Shotgun isn't ejecting is because i'm not using Remington shells.

I'm not using 3inch shells. (Even though all I used in Alaska was 2 and 3/4 inch)

The shells aren't "Magnum".

The shotgun is dirty and needs a good cleaning. (I doubt this one)

Now what do you guys think? Feel free to add to the list. The Magnum part i'm kind of scratching my head at, I could find these rounds when people talk about them online, but never actually found any in person or online.

Thanks for any tips/advice/problem solving solutions!
