I don't care what you shoot an animal with, if the projectile does not hit the mark then you're in for work. Put it in the boiler room and forget about it, no matter what it is. Hit em in the guts, low in the leg, meat of the neck, below the spine in the meat again and you are more than likely tracking... for a long distance...
While high velocity projectiles with a lot of energy do kill partially by inducing shock, for the most part all projectiles work the same way. They penetrate and rupture tissue and bones and cause death by disrupting, degrading or damaging the lubrication and or air intake systems...
