Paper

[Trapper]

Here is my opinion, I have not been doing this but a few years. I patch to just under bore diameter by .001-.002. The paper I use is 9# 100% cotton. My understanding of how paper is made is that the more cotton content the less fillers are added. It is the fillers that are abrasive, so being a welder/fabricator/machinist for the last 30 years the less abrasives I run down my barrel the better. I also think that 2 wraps of paper should not be thicker than the depth of the riflings. That way it is sure to get cut all the way thru for confetti at the muzzle. Less chance of paper making its way all the way to the target. There is my 2 cents, works for me, I am not a competitive shooter Just a hunter.
