I always run oil down my barrel when it is going to be stored for awhile. But I never put so much in it that it would run down into the action. Just a little goes along way to keeping moisture out.
When I'm going hunting, I do not clean my barrel. If it is clean and oiled, I go check my zero at the range a few days before my hunt and shoot the oil out.
ALWAYS HUNT WITH A FOULED BARREL!
I normally will let a dry barrel sit in the safe for no more than a week without oil.
If it's not far, it's boring.
