The 1777 Charleville was considered by most Europeans as the best musket in the world. Prussian tests, for example, showed that Russian muskets were 1/3 less accurate than the weapons wielded by their foes. It was also distributed to the Americans, and later became the basis for the pattern of the Springfield Musket 1795. They are 60 1/2 inches, with a 45 inch barrel, and have "U.S." stamped on the butt stock. The French Charleville musket was considered by many Russians as the lightest and best made of all the European muskets. In comparison to the French musket, the British Brown Bess was larger and more durable, the Prussian, Swedish and old Russian muskets were considered as unwieldy. Napoleon was not impressed with the Austrian muskets. He wrote in September 1796: "We have a great quantity of muskets, but they are Austrian, and weigh too much. Our soldiers cannot use them." (Boycott-Brown - "The Road to Rivoli" p 441)
Major Hans Boersma (Netharland infantry) writes, "The reason the (Dutch) Jagers nonetheless received the Brown Bess is probably because the French muskets ... that were still around in some numbers were in a very poor condition. In fact, the ballistic performance and maximum range of the Brown Bess was inferior to that of the French Mod�le 1777 Corrig� � something that was recognised in the high command of the Netherlands army where the issuing of the Brown Bess was seen as a temporary measure. As early as August 1814, while the Brown Bess was still being widely distributed, it was decided that the French musket would become the standard infantry firearm for the Army. It would be produced in the Netherlands as the Model 1815, having a slightly shorter barrel than the 1777 Corrig�."

oh and one more thing - the reason for aiming higher to shoot further is because lead balls are shot instead of bullets and that the balls ranged from 11 to 13 mm or more and because that normal musket wasnt rifled and didnt provide the same stability when shot
