My neighbor has a Remington 1100 that is not ejecting shells unless they are 3" mags. I knew these guns had a reputation for being picky with game loads, but I couldn't believe it when it would not eject 2 3/4" slugs when we tested it. We fired two - the first moved the bolt back about halfway and the second didn't budge the bolt at all. I am not the expert when it comes to autoloaders since I mostly shoot pumps, but this has both myself and my neighbor baffled. I believe that the gun has hardly been shot except for the few rounds he has put through it thus far and, like I said, it has not ejected anything except the 3" magnum slugs. Any ideas on the root of the problem or where to start? Thanks.
