It is probable that many of the victims survived due to him using a 5.7mm firearm. The number of deaths would likely have been higher if he had used a gun which fired the far more common 9mm, 40s&w, or 45acp jacketed hollow points.
If he’d been shooting any of the rounds you mention, there’d have been more fatalities.

Depending on where they were hit, one soldier was on TV today and said that he was not actually hit, he had a round in his boot. Even a fifty caliber won’t kill anyone if it only hits a finger.
