Last weekend's Baltimore Antique Arms Show was something of a buyer's market. Found a very good Harpers Ferry .54 caliber 1803 rifle dated 1815 at a very reasonable price. Sported a reconverted lock and Hoyt rifled liner. Took it to the range yesterday. Initial loads were 55 grains of FFg under a .530 ball wrapped in a thin lubed patch. It ate up the patches, leaving charred fragments down range. Used an old trick I'd learned from a "Muzzle Blasts" article in the 1950s: topped the powder charge with 2 CCs of Cream of Wheat. Accuracy improved greatly and recovered patches were perfectly intact. Clean up was easier. Ignition instantaneous and almost sure. A new favorite range companion!
