Marlin glenfield model 778 12 gauge pump, it is a older gun, i know my dad had it for a awhile but i couldn't tell you the exact year,
i use this gun to shoot trap with, i love it, i been having this problem with it when i shoot, we usually do 2 rounds at a time, when i first start shooting the gun ejects shells fine but it seems that as the gun warms up and gets hotter and hotter that it will not eject shells, i can move the action back but the shell stays in the barrel, it doesn't happen with every shell either, my uncle said it was the extractor, so he took it apart and filed and sharpened it and said that should do it but it didn't, i have tried all different types of shells and it doesn't matter
