RE: Does Kinetic Energy = Penetration?
<BLOCKQUOTE id=quote<font size=1 face='Verdana, Arial, Helvetica' id=quote>quote:<hr height=1 noshade id=quote>Exactly. I'm asking if you go to heavier arrows for heavier game, isn't that an admission that light and fast has it's limitations? If they have a harder time doing the job on a larger animal than a heavy arrow, how can the heavy arrow be any less effective on a deer? <hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face='Verdana, Arial, Helvetica' size=2 id=quote>
Arthur,
I agree with most of what you said in your last post, but what we are talking about are small differences. The reasons a heavy arrow may be less effective on deer are very slight. Penetration is no concern for me inside of 20 yards. A 430 grain set-up in a 70 bow is going to blow through the shoulder of most deer. At least it has for me. Still penetration edge goes to the heavy arrow when hitting bone. Trajectory may only be an inch or two flatter on a light arrow, in typical bowhunting ranges, but it's still an advantage when judging distances - even if only slightly. The other thing speed does, is it gives a string jumping deer less chance of escape when inside of 15 yards. Once again, I'm not talking about huge differences, but it is a slight advantage.
I've shot both heavy and light arrows, recurve and compound for over 30 years and my gut feeling is that I have more confidence with a lighter arrow out of my compound. When shooting a recurve, I have more confidence with a heavier arrow.
