Thank you, Dave, for the advice and the pictures. I agree completely!
Fools sulphur,
I applied a thin layer of Vaseline to the bottom three flats. I think I read that somewhere.
After I shot it the other day and after I cleaned the rifle, I wiped the exposed barrel flats and lock with a thin coat of Birchwood Casey's Barricade. It's going to a be trial and error deal I figure. May have to use a little 0000 steel wool from time to time.
Anyone else have a tried and true method of maintaining a barrel in the white?
