This doesnt sound right
 

alright this has to do with KE


with one setup I can shoot 383gr arrow

with the lowest setup being 65lbs and 28"
highest setup being 73lbs and 28.5
with 16 grains on the string these will produce 269-277 fps respectively, ok? But the KE according to a fill in the blank site will be 61-65ft lbs



the other setup I can shoot 409gr arrow
same weight ranges but this time the fps are 260-269 respectively, according to the KE site these 2 setups will have the same amount of KE.


Is this right?

RE: This doesnt sound right
 

Using both your highest velocities yes this is correct.but don't forget to include momentum;)another juicy aspect

RE: This doesnt sound right
 

Yep!!!

RE: This doesnt sound right
 

momena...what? [8D]

RE: This doesnt sound right
 

wouldnt KE be the measure of momentum? so to speak

RE: This doesnt sound right
 

No it would not so to speak;)

Momentum is a much better indicator of penetration than KE. KE is better suited for bullets because the bullet is actually transferring its energy to the animal to kill it. Arrows kill by cutting so you want to be able to penetrate the arrow thorugh the animal.

It doesn't really matter with your set up though. You have enough momentum and KE to kill any deer in the woods.
