Default RE: Kinetic energy VS. Arrow speed

IMO, more ke and momentum is "better" only to a point. Once you start driving arrows deeper and deeper into the ground after passing through, more energy is only wasted and that wasted energycould be used to flatten trajectory.
That's a good idea. And, as long as you hunt nothing larger, tougher or meaner than whitetails, I guess it's plenty valid. However, since hunting shots don't exceed 30 yards in most instances, trajectory is extremely overblown. In my opinion, since aflatter trajectory is practically meaningless at 30 yards and less, it's best to use that excess energy to give yourself a surplus of penetration potential for those times when 'just in case' comes into play.

Say the arrow hits a small, unseen twig before it gets to the critter. The lighter, faster arrow will be deflected further off course than the slow one. The perfect heart shot could turn into a perfect gut shot with a light arrow while the heavy one might still get lungs/liver.

Say the animal spooks and spins at the shot, and that perfect broadside shot turns into a rump shot. Where you needed only 18" of penetration into ribs and organ tissue to bury up in the mud on the other side turns into a situation where you might need 30" through heavy, dense muscle, guts, stomach and diaphragmjust to get to the vitals. The light arrow might not retain the 'punch' to do the job.

SurelyI am not the only one who is afflicted by Murphy's Law when I'm hunting!

If you haven't read Ashby's first study and seen his reports on his current research,and if you can keep an open mind about something you read on a traditional website - I've learned that some people don't have the intellectual capacity to do so - you might find it some interesting reading. Might even modify your thinking about how much 'punch' a high KE light arrow actually has vs a heavy arrowat much less KE.

I would highly recommend it asrequired reading fortraditionals but alsoanyone who shoots a bow on the light end of the KE scale, or wants to hunt very large animals with a bow, or just wants to know how to use arrow weight and broadhead selection to get the most deadly arrow possible from his setup.
