RE: Kenetic energy
I shoot a hoyt magnatec 70# with a 27 1/2 inch draw 28 inch 2315. 125 grain tip 547 grains total weight, on a scale. It comes off my bow at 231 f/s through a crono. My bow is at it' s max weight. Though paper it just leaves the three cuts from the fletchings right off the bow and at about 12 feet.
