I have just recently switched over to shooting black powder out of my 45-70 Pedersoli Sharps. I just love that smell and the sight of a plume of smoke being fired from the barrel. Also I guess I'm influenced by the movie "Quigley Down Under". Those of you that have seen it will understand. Oh I almost forgot to mention that my model is the "Quigley" model. Anyways so far I am very pleased with the results. The question that I have is how does one clean the very bottom inside of the cases. I used a brush to clean out the inner walls of the cases but upon inspection I noticed the bottom of the case was still dirty.

Does anyone have any ideas or sugestions on how to get that particular part of the case clean?
