RE: Hunting: Oil or No Oil?
As for hunting guns and rifles, for deer hunting. I don't oil my rifle (Remington 700) until the end of the season unless it gets soaked in rain. It may get a few spots on it here and there and may not look brand new, but I USE my guns and rifles just about everyday during season so I don't want to spook a deer with the smell.
I agree that people don't clean their guns enough. They just keep adding oil and adding oil. It builds up and gets gummy. I like to take mine apart after ever season and strip all of the oil out of them. Polish them up then put some good clean oil in them.
I've seen more guns mess up b/c of over oiling and gumming that being just plain out dirty.
