I've also heard that the shot::hit ratio at Borodino was something like 800::1.
I dont doubt that a trained man with a musket could make a shot, with a bit of luck, at 250 meters. But that would require a veteran soldier, with some skill, who would probably be in a light/jaeger unit, not the line.
Hell, the Russians didnt even bother putting sights on most of their muskets. Although that was mostly because they figured muskets were for wusses and REAL men used bayonets.
