Mike Roberts: YOu are absolutely correct. And I think every guy over 15 years of age read those histories, and want to try to shoot a ML rapidly by pouring powder out of his horn into a barrel, then spitting a ball down it, thumping the butt of the rifle onthe ground to seat the ball, and then firing it, just like that thar fella did! I have supervised shooters at my range to do this, but do it safely, so they can get it out of their systems.
Its like fanning a single action revolver. Everyone who buys a SA revolver at some point wants to fan it, and see what they can hit.
What I did to help these NL shooters live their fantasies, was first make them run a damp and then a dry patch down the barrel to make sure there were no embers glowing down there, and to clear the vent or flashchannel and nipples. Then I let them pour a charge of powder into the barrel out of the powder horn. We then had them put the plug back in the horn, and put the horn on the loading bench behind them. They then put a bare ball in the barrel, and thumped the barrel on the ground to seat the ball. But, before they were allowed to fire the gun, they were required to use their ramrods to check to see that the ball was seated all the way down on the powder, and was not a bore obstruction.
Then the flintlocks were checked, to see if any powder made it out of the chamber into the flashpan. If not, the pan was primed. The Cap and Ball rifles had perdcussion caps put on them, and then the guys were allowed to fire the guns at a 25 yd target, turned around, so that they were shooting at a 12 inch square paper, about the same area as the torso of a man. Some hit the paper. Most shot over, or under( mostly under) the target. All learned a valuable lesson, particularly when they then cleaned the barrel for their next shots.
