I shot 45-70 at Muster this year, I used a 405 grain bullet over a wad and card (got those from track of the wolf) with 60 grains of ffg Black Powder. I shot all day, actually placed 3rd (I think) and clean up was a breeze! I put balistol down the barrel, and ran a bore snake through three times, wiped it down and repeated. All clean.
