KE reamains constant?(roughly)
So...If I have a bow with specs as such
60#
30" Draw
350 grain arrow
250 fps = 48.58 Ft/lbs
My K.E. will not change significantly unless I change...
A. Draw length
B. Draw weight
C. New Bow<img src=icon_smile_big.gif border=0 align=middle>
So when looking at specs I can get a pretty good idea what the KE will be from the IBO speed (- for string accesories)even if I shoot a heavier arrow? So the KE is a rough way to measure efficiency???
Yikes! I just wanted to shoot a deer and now I'm back to Schoolin'!lol
