Anyone using Winchester Super Ranger ?

[on_one_wheel]

Has anyone else noticed corrosion issues after using Winchester Super Ranger 12 gauge 2 3/4 inch 32 gram BB.

I can't knock thier performance. They're great with my ic chokes, tight patterns out to 25 yards, 1350 fps and they eject easily but they seem to be very dirty and wil corrode the barrels over night if they aren't cleaned or at least oiled after use. ( like when I get home at 3am and cbf cleaning the tubes. )

Ps. Yes I know its time for something with chrome barrels .

Super rangers in #4 are my general purpose 12ga cartridge- haven't noticed any excessive dirtiness etc but i always clean when I get home.
