i agree with dwd. arrows kill by cutting vitals; lung, heart, vains, arteries etc. bullets kill by shock and trauma + a hole through all that. the more energy transfered with a bullet the better..the harder it hits and more damage it does. arrows dont have alot of energy to start with. comparing 2000-3000lbs of KE of a typical deer rifle to 35-70 of a typical bowhunting bow. theres just no energy TO transfer with an arrow. i much rather have a arrow slice and dice and pass through giving me 2 holes in the cavity of an animal than not have a pass through. just my thoughts. i just rather watch my arrow zip right through and be stuck in the ground.
