[hockeybum]

hey guys. my 11-87 won't eejct 2 3/4 shels for some reason. i wen't dove hunting yesterday and it wasn't ejecting 2 3/4 shells. my dad and i have probably shot around 100-200 shells through it. the gun is an 11-87 super magnum special

this is the link to the gun

The first thing I would do is clean the gas system and oil it... a lot of oil.
I would also get a new O-ring seal.

It may not cycle really light 2 3/4 loads, I only use hot loads (1300fps) in mine because theres no recoil anyways.
