SPG Lubricants Black Powder Cartridge Reloading Primer

From the introduction of the book: Steve Garbe and I [Mike Venturino] are collectively putting what we know about loading black powder in single shot cartridge rifles into this book. The way we tell to reload black powder herein is not the only method. It is merely our method. We freely admit that we dont know everything. As you will gather from further reading, we dont even agree about every detail, but we sincerely hope that what is here will be an aid to the reader.
