I've been under the impression that for best accuracy you should remove all the copper out of your barrel periodically. I recently read a review of a magpul dynamics precision rifle class where the instructor states he never removes his copper, and the rifle stays under 1/2 moa.
Thoughts?
Also, for cleaning your barrel of non copper fouling, is hoppes #9 sufficient, or should I look at other solvents?
