I had the same gun and same problem.
I found out that because it is a older model that you have to use a little more force and speed when you eject the spent shell. It should work because i have the cheapest wal-mart shells you can get and mine works just fine.
Ammo, parts, dirty
If it's a 16 gauge shotgun, the shell length is 2 3/4 inches.
12 gauge
Yes
Take it to a qualified gunsmith to find out for sure. Sounds like it could be a problem with an extractor or spring.
Try cleaning it, different ammo. If that doesn't work, take it to a gunsmith.
You need the services of a gunsmith. There are about a half dozen or so reasons if not more.
Any of the following could be the culprit; dirty, ammunition, springs. Take it to a gun smith.
Model B 80 may not eject low base shells due to insufficient energy generated during the firing cycle. Low base shells typically have less powder, which can lead to inadequate force for reliable ejection. Additionally, the extractor and ejector mechanisms might not be optimized for handling lighter loads, causing failures to eject. Ensuring the firearm is clean and well-maintained can also impact its performance with different shell types.
Its quite simple as that it ejects the shotgun shell out of the gun after it has been fired but this depends on the type. A double or single barrel shotgun would only eject the shells when u hit the release mechanism to reveal your side of the barrel then they eject out.On any other type shot gun where u load 8 or have a clip they generally fling out the side when re-cocked or if automatic they do this automatically. Hope i helped
First make sure that your shotgun can cycle 2 3/4 inch shells. To do this, read the barrel, if it say 2 9/16 shells then that is your problem. Early 16ga. Browning's were made to cycle 2 9/16 inch shells. Next, check your ring setup inside of your stock, it may not be set properly.
Odds are it isn't a Remington at all, but rather an Ithaca Model 37. To my knowledge, it was the only bottom-eject pump shotgun ever made. As for value; any gun (or anything else for that matter) is worth whatever another is willing to pay for it.
