For me, it was hard to believe the number of steps involved in just loading the musket, and then what it took to be accurate.
The original drill required twelve steps to load and fire. Americans, being American, reduced this number to ten.
1) Bite off the base of the paper cartridge
2) Prime the pan, placing the cock is in the half cock, safety position
3) Close the pan
4) Place the butt on the ground. Pour the remaining powder down the barrel
5) Place the cartridge in the muzzle
6) Ram it home
7) Pack the powder
Cock the musket
9) Present
10) Fire
Then, the "delay." You pull the trigger, the hammer falls, a cloud of smoke and fire right in your face. Half a second later, when you are starting to think about misfire procedures, BOOM, a .69 caliber ball goes down range. It takes a stout human spirit to see that flash in the face and calmly await the BOOM without a flinch.
Imagine having to hunt with this thing.
