Cleaning is just like ammo. It varies by rifle. My .270 BAR likes to be somewhat dirty. I know people with the same rifle who say their rifles shoot better clean. But for my .270 The only cleaning it gets from summer practice through the end of deer season is a dry patch and a little lube on the bolt. My -06 on the other hand is more fussy. I don't scrub it down until after the season but after every target session it gets a couple of wet patches (Butch's Bore Shine) followed by dry patches until they come out clean.
