Then you pour in the desired amount of powder (by volume)

In this case, I started with a load of 30 grains of FFFg Black Powder.

Then place a greased patch under the ball, and start it in the barrel with the starter.

Then a rod is used to fully seat the ball tightly against the powder charge.

When ready to fire, place a percussion cap on the nipple and you are ready to fire.

This small pistol was made to be used at "across the card table" distances, so that's the range we will shoot at, about 4 or 5 feet.

Here's the shot.

Fire and smoke!
