Hey all, I have a new Mossy 590a1. i put about 45 rounds through it and have had an issue since the 5th round was shot out of it. the magazine doesnt eject properly so the round just sits in the magazine after pumping after each shot and so it fails to load into the chamber about 75 percent of the time. i lubed it up but no difference. has anyone else had any issues like this? any suggestions or ideas would be much appreciated. thanks in advance!
