Are you shooting that many deer that you have to clean your gun during the season? I clean my gun before the season opens, make sure it' s still sighted in, run a bore snake through it and it doesn' t see hoppe' s no9 till after the season. I think the smell of gun powder is less alarming than the smell of oil. Though I do have 2 different shotguns and usually alternate between them depending upon the cover I' m hunting.
