Winchester pump problem
I have a Winchester model 1200 that I use for shooting clays. I purchased the gun used at a pawn shop 15 or so years ago. It has seen many cheap 100 round boxes of bulk walmart ammo (at least 10k by me) and has worked flawlessly until recently.
When I chamber a round and fire, the action returns back and ejects the shell on its own unless you hold forward pressure on it. In other words, if you were to fire a round holding shouldered with only one hand on the trigger, the empty case would eject. The shot still seems to fire normally. I dont recall it doing this before. It has always been regurlarly cleaned and lubricated and stored in a proper enviroment, no signs of rust or obvious wear. Any Ideas on the cause?
