I have a fairly new 10/22 that has, up until now, been freakishly reliable. Lately, however, when I have taken it to the range and loaded it up the first round would fire just fine but the second would not. When I pull the trigger nothing happens, not even a click. The trigger just feels all mushy. If I eject the round and rack the nest one it will fire but not the one after that. Has anyone else had anything like this happen to them?
