My father has this Winchester pellet gun that i used to play with as a kid it was black and had the night sights on it and so as my little brother started to play with it one day he put a match stick down the barrel in front of the bullet cause the force would cause the match stick to shatter when it hit any target and after a few times the match stick must have gotten stuck on something and then clogged the barrel. Being that it is .177 round i tried to get a cleaning rod down the barrel to try to push it out but the barrel is to small and i have taken a coat hanger apart and tried to do the same thing but the wire hanger is to malleable and i have run out of ideas.
