So what’s the difference between a trade rifle and a muzzleloading rifle? I understand the difference between a rifle and a musket I think... the rifle has rifling and the musket is a smoothbore, but what’s the difference then between a smoothbore musket and a Fowler?
Ah, none
From 1791-1821 the federal government wanted to control Indian trade and tried to stymie independent trade. It set up ‘factories’ across the frontier, ie trading post. The government contracted with rifle smiths to make an inexpensive rifle in general American pattern to trade with the indians. Many of these got in to the hands of frontiersman as they were solid and cheap. It was done to counter British trade as they were supplying smooth bores.
After 1821 private companies took over Indian trade and they bought from the same suppliers. American Fur and Rocky Mountain Fur put the same contract rifles in to the hands of their employees that they were selling to Indians, although they also offered smoothbore copies of English guns.
Musket started out as a big two man gun that was used something like SAW, guarding the flanks of the military formations. They were half artillery half shoulder gun. And could be used at much longer range then shoulder guns.
They shrunk in size to the muskets of the late seventeenth through the eighteenth century.
Then in the middle of the nineteenth they got rifled, ended as a gun name with breechloaders.
Today if one says musket we are referring specifically to big bore long shoulder weapons made to take a bayonet and stand up to hand to hand fighting, mostly flintlock.
Back in the day the name was used at times for the smooth bores made for trade or the guns carried about ships for self defense, or the guns made for militia men requirements.
Fusils, light musket, Fowling piece, musketoon, carbine are all the same gun with minor stylistic changes.
Today if you call a fusil or a Fowling gun a musket it means your a newbie, when you use the ‘right name’ it shows your an initiate.
