  1. I'm trying to determine the approximate muzzle velocity of 18th century muskets. I have data that I think would allow this calculation: a musket ball fired from a gun with the barrel elevated 15 degrees travelled a distance of about 1600 yards. The ball weighed a little over an ounce. I assume it was .69 of pure lead and weighed 495 grains. Given this information is it possible to calculate what muzzle velocity is necessary to throw the ball that far? I don't want to assume velocities obtained with modern black powder. The powder was weaker in the 18th century. For example, a typical load for a Brown Bess (.75 cal -- they used a .69 ball owing to fouling) was as much as 230 grains. Today 100 grains is typical I suspect that some form of artillery table might provide the necessary equations. However, I don't know where to begin -- that's why I'm posting this. If anyone can be of any help, I will very much appreciate it! If someone could do the calculation, (I don't need precision -- simply an estimate of the mv), that would be great!!! Thanks.
