You crack me up.

You have no proof that the heavier arrow is going to do more damage but from one guy's experiment and swallow it whole like it's from God himself. Dead is dead, period. bottom line. End of story.

You keep touting that 650 gr is the minimum to break heavy bone is more deadly. your first comment clearly states that a 650 gr arrow is needed. Therefore, it's easy to deduct that you feel that is the minimum that anyone should use on deer. It's really an easy deduction to make. But then you back peddle and say you don't think that way. No where in Ashby's report does it say 400 gr. he clearly feels it is 650 gr. and since he obviously the only person in the world who is right and as a result makes you right then 650 gr should be the minimum.

Shooting over a deer is shooting over a deer. Whether you use a bazooka, arrow or missile. And if they do hit it with a bazooka there will be nothing left. You honestly do not get a joke do you?
