I guess it's a matter of the definition of "heavy". To me, 460 grains is medium light. I would never be confortable hunting big game with something that weight.
bigcountry, I'm not trying to nitpick on your weight choice, I just think those reading might benefit from thinking about what really qualifies as performance when it comes to shooting big game.
You know straight, never had a problem with light arrows, heavy arrows. Killed dozens of deer without problem there. I think people overthink most of this. I know I used too.
