If we solve for K1 and K2 we get K1=-.0023 or .23%, K2=-.0015 or .15% That represents the change in velocity per yard, and therefore KE and momentum.Technically the bow isn't an energy generator, it's a storage device that holds the energy you put into it and then transfers that to the arrow. The valid part of page 47 is that at a set weight and draw length, these would be your comfortable max weight and draw length, energy is the same as it leaves the string, no matter what arrow you shoot, as soon as that arrow leaves the bow though the arrow does what arrows do which is slow down and loose energy, how much it loses is directly related to the arrow mass
So you retain .08% more KE and momentum with the 650 gr arrow.
Drop for the arrows the arrows in inches at 10/20/3/40/50 yards:
K1 = -2/ -7/ -17/- 31/ -50 ( 360 gr)
K2 = -4/ -14/ -30/ -54/ -87 ( 650 gr)
Got that from this thread, courtesy of @Plebe if I remember right.
Is the juice worth the squeeze on those heavy arrows? Shoot what you want. I look at that math, and the 12 factors and say no to that heavy of arrow
