I guess my only stink with that Pa, is I would wouldnt be suprised at all to say almost or slightly over 70% of the speed bow folks to be using range finders. That figure could and probably is quite higher.
That said, if the only loss is pre determining distances and or marking them out prior to a hunt in some way shape or form for a slower heavier, higher momentum arrow and even some arc to it, heck for that matter, what you all would consider low KE 30-40foot poounds, And achieve almost total penetration on something oh, say the size of a average bull moose
VS
The guy shooting screaming super light arrows arrows for the sake of his/her lack of ability of judging yardage in which case he more likely owns and uses a range finder to help him/her aid in pin point accuracy, shoot and wound a moose in only hitting a rib bone.
(Woody, you can go ahead an pipe in here on knuckleheads moose experience before he left)
Now does it really matter, you aint hunting moose.....probably not. But it does when a situation like Krisken states, in shooting a shoulder and getting no penetration. I think I preached that gig back from post one......a worst case scenario.
The problem with the two equations is one factors in both speed and weight un biasedly. The other is speed biased.
One is also measured only till impact where the other is what is going to help carry the object of concern through, be it a bullet, arrow, slugs. (the only difference is in how they kill).
There is also some good reading on Bob Robb' s elk hunting book. Col. Ret Bodington has a great article in there. You would be amazed to see some of the same things when it relates to the thought process and reasonings to penetration from rifles to bows. Just something else to get a good foundation of knowledge from even if its from the dark side .....[&:]
Alaska is one of the few states I know of (actually the only but I know if I say only I' ll be wrong), to have an arrow weight standard.
There is a slight flaw to even this. Espically when they are trying to madate a 900 grain arrow for critters like moose and bison, and a 750 grain arrow for caribou and blacktails sized critters. Its a point of dimishing returns. I dont think many folks push the to heavy issue to much as they really feel to heavy isnt an issue. I however feel differently. I also feel this is where I agree with Pa a slight bit albeit for different reasons.
I also was helping out the state in its bowhunter ed classes. I think what bothered me the didnt have anything to do with light speed folks. It was the amount of archers and " bowhunters" out there that just couldnt hit the broad side of a barn from the inside out! 5 of 8 arrows in the kill zone, with 2 arrows in the high 20 yards, everything else 22 yards or less on deer sized animals, and they manage to fail time and time again, thats with the use of range finders, sights, optics, let offs, release, gizmo this gadget that. It has nothing to do with them not handling speed up here, they cant figure out what end is up!
