RE: Heavy arrow, more KE....light arrow, more speed..??
Someone argue with this..... Shot from the SAME BOW, nothing hypothetical here. Real world numbers.......
350 Grains at 300FPS yields 69.87 ft lb KE
500 Grains at 254 FPS yields 71.55 ft lb KE
At 350 grains and 300 FPS your arrows trajectorydrops 22.92 inches from 20 to 50 yards and loses 4.15 ft lb of KE from 0 to 50 yards.
At 500 grains and 254 FPS your arrows trajectory drops 34.34 inches from 20 to 50 yards and loses 3 ft lb of KE from 0 to 50 yards.
SO, in essence you flatten your trajectory 11 1/2 inches while only sacrificing less than 2 ft lb of KE with the lighter faster arrow setup.
While I do not hunt at 350 grains, I am just proving a point here.
