From another thread:

The major was a regular at a shooting range I have a partner with. He used a FN 5.7 x 28 pistol. He was at the range this weekend and was very adept at shooting targets at 100 yards.

So your suspicions were on target. This was not a guy who "snapped."

Thank you. It’s so hard to live with the fact that I can tell when someone’s pants are on fire and they are unable to feel the heat. Bain of my existence. Thank you. I try to come off as subtly as I can, but sometimes I feel the urge to spell it out in boxcar letters... YOUR PANTS ARE ON FIRE!!! ;-)

He didn't have to hit all his targets with every rounds as some have speculated. This gun has penetration power. A shot would go through one victim and into another in a room packed with people like sardines.
