thanks for asking on mine and your behalf mounting man, on my deer rifles what i've been doing is do a complete cleaning after the season when the next season starts i'll fire my 1-3 "throw away shots", after this for the remainder of deer season i'll run rem oil down after a shot(s), and then run a dry patch down the tube but leave the copper fouling, or at least i don't use a nitro /copper solvent until after the seasons over, my deer rifles may be shot 10 times during the season at the most, if i was real lucky. like i mentioned in the other post if i start seeing erratic/errant shots on my others i'll clean till the green is gone..but i have always shot a fouling shot or three on my hunting rifles after removing heavy copper fouling, best of luck everybody and good shooting...........
