I found a Staples Store not to far out so I made a trip to get a few things I needed and I also found a roll of their 8# paper 12"X50 yards so I picked it up. I measured several strips I cut and this stuff is thinner then the Seth Cole 55-Y. It measures .001335" to .001293" I will throw it up on the shelf and call it leaver right paper (leaver right there)This paper is Staedtler brand 8# a Canadian mill.
It looks like a straight wood pulp paper and it has enough sizing in it to keep a felt tip from leaking through so it should polish the bore in fine shape.
If some of you have a three thousand deep groove and a over seized bullet this should work pretty well. I have a rifle with a groove depth of three thousands but I don't have a tight pp bullet
