"Weren't the colonial muskets .50 caliber?"
Nope, .62, .75, .78, and up.
Caliber .69 to .75 generally.
Larger--mostly about .70 caliber. If you got hit by a ball from a Brown Bess, chances were that was the last thing you'd ever be hit by.
Actually they were bigger than .50, if you are talking pre revolution and for some years after he revolution. Most military muskets, and therefore civilian also, were about .72 caliber. .50s came later during the mountain mans heyday.
