Из книги Christopher Duffy. Military Experience in the Age of Reason. c. 155:
"It is likely that E.Mauvillon used the material which came to light on this occasion in order to write a passage which caused a considerable stir in military Europe:
According to my sums, the Prussians fired 650,000 rounds of musketry during their advance at Chotusitz, and the enemy lost scarcely 2,500 dead and as many wounded. If you subtract the men who were killed or wounded by the sword, a mighty great number of rounds must have gone astray! (Histoire de la dernière guerre de Bohème, 3 vols, Amsterdam, 1756, I, 100–1. He discounts the effect of artillery, which was considered of little importance at that time)./
By Mauvillon’s calculations, the ratio of rounds expended to deaths sustained by the enemy therefore amounts to about one in 260, which equates roughly with the one in 200 given for the English fire at Wandewash in India (1760), one in 300 for the American fire at Concord (1775), and one in 460 for Wellington’s fire at Vittoria (1813). The lethality is diminished by the allowance that must be made for the contribution of the other weapons, but increased by the knowledge that about half the rounds nominally ‘fired’ were probably thrown away by the soldiers (Ligne, 1795–1811, I, 49). An altogether higher rate of kills was achieved by riflemen who were shooting at carefully-selected targets. The thump and whistle of a musket shot was much less feared by troops standing in line than the crack and buzz that told you that jägers or American back-woodsmen were at work. In America, unlike the theatres of war in Europe, the life of an individual was sought ‘with as much avidity as the obtaining of a victory over an army of thousands’ (Anburey, 1969, I, 331)".
То есть коэффициент европейцев во второй половине XVIII — XIX вв. (плюс-минус 200-300 пуль, затрачиваемых на убийство одного неприятеля) оставался где-то на уровне XVII века. Насколько я понимаю, серьезной разницы в убойности стрельбы между пехотой Восточной и Западной Европы не было.Польская, русская или шведская пехота XVII-XVIII вв. демонстрировала меткость уровня британской (которые, как я понимаю, в целом стреляли, как и все, кроме отдельных битв) и прусской пехоты XVIII вв.
За наводку на книгу - большое спасибо уважаемому sovice_snezni.
