I inherited a 2200, basically same action from my grandfather 20 years ago. He used it hard and neglected, I have done the same. Ihave removed the action and found teaspoons full of crud and spruce/fir needles, never had a ftf or jam. Pop used alot on sal####er (ducks/turs the odd seal) and I have shot hundreds of rabbits, ducks, grouse,partridge and tree rats,2 moose and 1 caribou with it. It has a 2 3/4 cham, no vent rib, no blue left on it,the aluminum action is shiny and the wood beaten and battered. I still use it and have no interest in stashing away or replacing her, shes a doll and still goes boom when the trigger is pulled.
