I want to add that I DO believe in oiling my guns....but I do it when I put them away. During their use at the range or in the field I rarely, if ever, have any lube of them. And if I do, it is only if it is above 40 degrees outside....and a dose of damp weather. They might sport a thin film of silicone...
But when I put them to bed in the gun locker, they have been given a close cleaning, inspection, and wiped down with a film of oil for storage.
Once out of the locker for use, I make sure they a clean as a whistle and bone dry....maybe a little graphite around the bolt.
The big thing is to make your gun work well and keep away the rust. Whatever you are able to do to maintain the "health" of your guns while protecting the flawless operation is everybody's goal.
