I have hunting arrows weighing 330 grains. I also have them weighing up to a tad over 500 grains.
It's pretty narrow minded to think that a light or heavy arrow is the only way to go.
Things to consider are expected shot distance, size of game you are after, resulting KE from your setup with a certain weight arrow.
I'm not a Gun hunter, but I doubt a serious Big Game gunhunter uses the same caliber and weight of bullet for eveything he hunts.
I wouldn't go Antelope, or Mule Deer hunting with a 600 grain arrow because the KE with a lighter setup is still more than adequate, and the flatter trajectory is a big advantage.
There arethings that IMO are more important in a great hunting arrow than just overall weight.
Spine
FOC (minimum 12% but I prefer closer to 15%)
Adequate fletching
etc.
