Now that we're talking about smooth bores let's not forget the Brown Bess. Accurate enough with a patched round ball for woods hunting. Can be loaded with shot for birds, bunnies and turkeys. Paper cartridges for sustained fire against colonial rabble. Ruled the world's battlefields for 125 years. Huzzah!
My "Bess" of choice is my Light Infantry Fusil. Let's say a 2/3 scale Bess in "carbine' bore! Served me well at Cowpens on the set of "The Patriot" too! Several pounds lighter than the standard Second Land Pattern Musket.
