She lit a long match and touched it to the end of the line of powders. The modern rifle powder flared and burned slowly, the pistol powder burned a good bit faster-then the black powder flashed wildly, gone in a split second.
”Good God!”
”Yes. That’s to teach you to respect black powder. Be careful when handling it, especially when you’re reloading black-powder weapons. A mistake can injure, potentially even kill you.”
”Great.”
Ann smiled. “Just keep your wits about you and practice. Now, let’s start with the components of ammunition for black-powder weapons. In most historical arms, there was no cartridge case, just loose powder, a projectile called a `ball’ and a bit of cloth called a patch, which is greased to help you push the ball down the barrel and to help prevent fouling. During the American Civil War era, a bullet called the minie ball did away with the need for a patch, but it never caught on well with hunters and sportsmen.”
Margo said, “Okay, ball and powder and patch. Show me.”
Ann demonstrated the whole loading process. “There are two important things to remember about blackpowder firearms. One, be sure the ball is seated all the way to the bottom. Check the length of the ramrod,” she showed Margo how, “to be sure you haven’t left a gap at the bottom between the back of the barrel and the ball.”
”Okay. But why’s that important?”
”Remember what I said about thousands of pounds per square inch of pressure inside the cartridge cases of modern guns when smokeless powder begins to burn? Well, black powder doesn’t burn, it explodes. If you leave a gap here,” she pointed to the bottom end of the barrel, “what you’ve done, essentially, is build a miniature bomb.”
