Indirectly, no....

I always verify the sight in of the rifle just before hunting and I DO NOT clean the rifle after that sight in check prior to the hunt.

If you live where the onset of rust is immediate (I'm in bone dry Colorado) and you run an oil patch down the bore to preserve the bore, then you need to run a dry patch down the bore to remove the oil before firing and yes, in that case if you want the rifle to return right to your prior sight in a fowling shot is recommended.

Hunting "back east" or in Alaska would be a different ball game and seemingly "moisture problems" are responsible for the demand for synthetic or laminate stocks and stainless actions and barrels. I'm a wood and bluing guy myself, but it works here.
