PROPERLY speaking, a Musket is a smooth-bored military long arm: 1777 Charleville, Sea Service Musket, Indian Pattern Brown Bess, Lee-Enfield MUSKET et cetera.
The other terms, a la Winchester and Savage, are regarded as obsolete, although they did look good in the catalogues. The gun companies were attempting to break nto the military market, so they put out MUSKETS and CARBINES, these being terms which were familiar to the military. SAVAGE even brought out their own cartridge (.303 Savage)as part of the attempt.
GAWDS! Can you even IMAGINE the problems with an entire Army equipped with `86 Winchesters????????????? I would NOT want to be their weapons tech!!!!
But it really is supposed to refer to a SMOOTHBORED long firearm. The French word is "fusil" and the French Army still calls its rifles "fusils", even though the things are rifled. Napoleon did not have a good opinion of rifles, refused to have them in his Armies. He lost, too.
