Okay, now I am confused. I read on one of the forums about accuracy and that cleaning of the barrel could affect same. The forum indicated that the zero would change after cleaning. I have always had the habit of cleaning my gun after using. I use a copper wire brush, then bore cleaner, the light coat of oil after cleaning. Is my zero going to change now??? It seems to me if this is true, I don't want to clean the barrel until after hunting season. Can anyone provide the straight scoop?
