Please bear with me, this may be a long-winded explanation.
I have a Winchester 101, 12ga. I've shot 4 rounds (400 shells) of sporting clays with it since I bought it used. First 300 shots, the gun functioned perfectly. Now I have an issue.
After the gun has been fired, it is extremely hard to break open about 1/2 or 2/3 of the time. I was fiddling around with it last night and noticed something. If I put the snap-caps in and dry fire it, it is stiff to open. If I open and close it without dryfire it is extremely easy to open.
It is different from a Citori, in that it doesn't need the recoil to set the trigger to the next barrel. Just pick if you want top or bottom to shoot first and then pull the trigger twice. Is it supposed to need the recoil, and that could be part of the problem, that the recoil system is somehow screwed up?
BTW, one other thing I've noticed is that while the safety slides up and back very easily, it is pretty stiff/sticky side to side when selecting the barrel. Could this be part of the problem as well?
Any help would be greatly appreciated. I am going to the range this weekend for some more SC, but am planning on using my A5, but I will probably take the 101 as well, and see if I can talk to the gunsmith.
