I am just getting started with this Paper Patch thing, very intriguing. I am shooting a Remlin GBL in 45-70. Bore slugged at .451 and groove diameter measured .458. I am using an old Lyman 457193. It is dropping at 409 grains with straight WW's and air cooled. I sized the Boolits to .452 and patched them with 16# notebook paper (can't find the green bar stuff around here). I ended up with a final diameter of .462. I am not sizing again, because I do not have a large enough sizing die yet. I loaded them on top of 46 grs of RL-7. It fills the case but not much compression. I am wrapping them to just past the step in the Boolit and seating and roll crimping just past the paper. I am lubing by hand with a 50/50 mix of LBT Blue and Vaseline because it was what I have. I have not tested it for accuracy yet, just seeing if it works. I have many questions, but would welcome any guidance from what you see from the picture. The paper looks like it is seperating/tearing between the GG's. They match the spacing of the grooves. The expanded boolit was dug out of a wet pine log. There is little to see at the base, it turned into a cupped base.
