Yes, 100 rounds per minute is less than 600, but it will still does a hell of a lot of damage. Just ask the citizens of Newtown and the survivors of the theatre. As far as your full auto point, the people should then feel lucky it was not full auto?
As for 30 round clips for hunting, keep the round to 5 round clips. As said earlier, a need for a thirty round clip in a hunting firearm is just a sign of a lousy shot.
No one i know is saying it's a terrible hunting arm, just not it's first purpose, nor needed to hunt.
