I was at the library today hoping to find a copy of Rifles of Colonial America, they did not have one, but I did find a book called Arms and Armor of Colonial America. I was leafing through it and found a desciption of a simple device that sounded pretty neat. It described a small block of wood slightly thicker than the diameter of your round, with holes the diamter of the round drilled clean through it. You would pre load it by placing greased patches over the holes and then plunking a ball in. Then, as needed, you just center this block over your muzzle and ram it down, no fumbling with pathces. Has anyone tried one of these?
