Ok - a second question: was there a dead zone as several authors have suggested between the range of cannister and shell?
Bowden in his book Napoleon and Austerlitz notes on page 73 that there was such a dead zone where the fire was ineffective (but not impossible to range the piece to hit that range).
Basically anywhere from 250-300 meters and 750 meters. These are general numbers. The point of his argument was that there was such a dead zone from the max range of cannister to the minimum range of shell.
