I hesitate to ask this. Can the Monty Python script writers please comment elsewhere. The guy at Virginia Tech used two weapons. Killed 33 and injured another 15. So, certainly 48 rounds fired. Some say they saw 'bullets' (plural) hitting so he was at least double tapping. I've solved the question of reloading - I think. YMMV What I would be interested in is the total number of rounds fired but this has either not come out or is lost in the volumes of reports. However, what might assist me is knowing whether there is any form of forecasting accuracy levels. What ratio between the average marksman's rounds fired and hits scored? I realise that FIBUA involves some supressive fire. I left that when the main discussion was long bows or cross-bows as best weapons. I have done the walk down a FBI street so have some idea of deliberate shooting. If he hit 48 people, is it possible to assess how many misses he had? If this is likely to open the doors to trolls, let it drop please.
