The Brown Bess was the main infantry battle musket used by all the troops for many years. It was battle-tested and very effective the way they used it. Since it could not shoot straight they simply had all the troops shoot at the same time and that sent a wall of lead downrange and that did a lot of damage to any enemy. The gun was huge, 75 caliber. That is compared to most of our muskets which were just 40 caliber. most of our modern hunting rifles are all 3o caliber. It was said that all the Brown Bess needed to be called a canon was a set of wheels.
