No one needs a machine gun to hunt deer.
Chances are you'd just mess up a lot of meat.
Most deer hunters will use only one or two shots to fill their tag.
The best, just one.
Consider, confining people to rifles with limited capacity is only incentive for them to be more accurate and
make every shot count.
Those were the guys who turned battles: the sharpshooters, backwoodsmen who hunted for the table and larder, who selected and removed enemy commanders from the field with accurate shots on more than one occasion.
If things go to pot, who wants to face a nation of snipers?
