I have a 20 gauge Winchester 101, 30" barrels choked full and full. When I acquired it a few years ago it was unfired since it was brought back from Japan in 1967. Since then it's been shot 3 or 4 hundred rds give or take.

Before I ever shot it I took the butt stock off and used spray cleaner and air pressure to clean any old lubricant off and then re-oiled with Wilson gun oil.

The gun shoots fine with pretty much all ammo except the White box Winchester you get at Walmart....save your Walmart jOkes.

The gun is hard to open with the Winchester white box 20 ga. ammo. My buddy shot it the other day and was struggling with breaking it open. I remarked...takes a man to shoot that gun.

With most other brands it's a little stiff but it's okay. Gun works fine with Remington Gun Club ammo but who knows their future.

Any thoughts other than don't shoot the cheap Winchester White box ammo ?
