check and see if a fog layer forms on the scope when you come in
Not this year.
Do you cover your muzzle? when in the cold, wet, damp weather?
No, no, no and no. This problem was occuring in cool, damp to dry weather. Although, our "dry" is similar to your most humid days in Idaho.
I think if I get the GM barrel for the gun I'm looking at I may go to 777.
thanks
