Powders are carefully measured and poured into the bores of the rifles. Lead projectiles are set at the bores of the rifled-muskets, tapped in slightly before ram-rods follow, in a clatter, to pack the powder as solid as possible for a consistent burn-rate. The percussion cap is placed over the nipple cone and the hammer is retracted. The rifleman takes aim at the target, steadying the long gun before squeezing the trigger.
If you are willing to learn, you will learn every single day of your life. If you are analytical, you will learn to tell the difference between what is fraud and what is truth. Unfortunately, not everybody is so keen on conscious learning throughout their lifetime. We see this if you were to set down a firearm on the table in front of someone like myself and someone who is wholeheartedly anti-firearms. Quite a few of the latter will be frozen solid with fear of what is nothing more than an inanimate object, and this is common knowledge. But, there is something about this reaction that is somewhat disingenuous.
