LOL I think that says....47 bullets? How is it possible for someone to fire that many bullets in that amount of time with those 2 guns? Reload factor?
98 rounds in a minute, including reloads, isn’t hard - especially when accuracy isn’t an issue. Assuming about 15 rounds per mag, that’s 7 mags including 2 already loaded, requiring only 5 reloads. Assuming a reasonable 2 seconds per reload for a motivated & moderately-practiced individual that leaves 50 seconds, more than enough when firing 2-3 rounds per second. Considering how far someone can walk in a minute, and the density of victims, the numbers work out fine. Historically unusual, but far from unreasonable.
