tex, for those figures, that is right where it all fell together like you said...just a nice balance of it all before you start eating speen and not gaining hardly any KE...

Jeff, its hard to explain....but what would hit harder?....a mack truck fully loaded doing 50mph or a mazda miata doing 90 mph? (bad comparison size is a huge difference but use your imagination....i know you got one ) think about it though...the lighter miata is traveling faster, but will be easier to stop because of its lightness...a sturdy brick wall might stop it...while the same wall will be laughed at by the mack truck....like i said...hard to explain...with deer, the difference probably isnt going to mean a whole lot....i dont know...i dont have the time and years of expirience and actual testing other than figures and my imagination and some reading and research....could get me an extra inch of 2 of penetration on a BAD hit when i need it...who knows...i could probably show it better with bullets....you can really see the loss of energy at longer distances with lighter bullets opposed to heavier bullets...im going to do ALOT of research and toying around before i buy a new bow/arrows....i will likely go with a speed bow...and throw some true LOGS on as arrows...aughta knock em off their feet! lol...DEAD is DEAD....we know that. my line of thinking is in times of bad hit...contacting a bigger bone than ribs...you and i both know STUFF happens...shots go astray...extra penetration and power can never be a BAD thing...

bob, point me in the direction of the Dr. Ashby studies if you can...i thought i had them somewhere but cant find them and never did get around to reading them fully....
