score:6
I have the following figures to hand for weight of shot and charge, for a range of weapons that may have been used by the Prussian Artillery during the Napoleonic Wars.
Shot (kg) Charge (kg) 12-pdr M1761 5.93 2.30 12-pdr M1768 5.93 1.60 12-pdr M1809 5.93 1.60 6-pdr M1762 3.0 1.40 6-pdr M1768 3.0 1.40 6-pdr M1787 3.0 0.89 6-pdr M1809 3.0 0.89 7-pdr M1762 6.54 0.90 7-pdr M1790 6.08 0.69 7-pdr M1809 6.95 0.69
I don't have the corresponding figures for range or muzzle velocity for these guns. However, given the intended use for the information, all of these weapons had sufficient range to cover a Napoleonic battle field.
[T]heoretical maximum ranges were usually unimportant. The Prussian General Monhaupt noted that 'a 12-pdr is able to fire its roundshot 460-600m further than a 6-pdr, but this has no influence on the outcome of the battle...a hit at such a distance is purely accidental'
It goes on to say that the theoretical advantages of the 12-pdr were 'often negated by its slower rate of fire'.
