Im heading to the patterning board in a couple hours and have an idea, curious on everyone's prediction. I thoroughly clean my bore between each shot and have noticed that there are strips of plastic that come out of the bore each time, which are from the wad dragging in the bore. My bore is polished to a mirror finish so I know that I will not get it any better, so, Im gonna try to swab the bore with mica dust or graphite powder to see if it will reduce the drag on the wad. Ill post up my results later but curious to see what you guys think. Will it Help or Not?
Sounds like a dusty dirty mess but im intrigued, keep us updated.
Philippe you were right. It was a mess. Had no affect on the pattern at all. Just gunked the barrel up that much more.
