I've always tried to put the rifles away, if I'm not going to use them anytime soon, with a clean bore and a light coat of Shooter's Choice. Never have had any sort of problem in doing that. But on the other hand, maybe an oiled bore (or whatever you use) isn't that necessary. When my Dad passed on, I got his old Ruger Ultralight 270. I know for a fact that the bore had not been cleaned more than every couple of years, because I did the only cleanings done on it. Dad hunted in eastern Louisiana and hunted on rainy days and dry days and whatever days came around. He rarely even wiped down the outside of the metal unless it was dripping water. When I got the rifle, the bore was dirty but not pitted, and shot like a champion. So after maybe 25 years of abuse, the bore was not damaged. The stock is pretty worn and a lot of bluing is worn off, but it really shoots great.

But...I'll still keep doing what I do.
