Hey all, recently picked up a used Wingmaster, while in the process of trying it out had a few issues. Occaisonally the gun would ftfeed a shell from the magtube- not shortstroking as the trigger would be reset, but no shell in the chamber. A couple of times, the gun would double feed- as in two shells would be released from the magtube on to the lifter. These malfunctions happened maybe 6 to 10 times out of around 200 rounds. Rounds fired were Federal bulk, Winchester bulk, and Winchester "heavy game loads" #2 shot. Any ideas?
