RE: Rocket Steelhead 125 test results OUTSTANDING!!!!!
thanks again 5-shot i need to buy some more heads today and i will have my arrows weighed so i can figure the KE actually the weight addition will boot the energy. but not as much as the arrow velosity. so it will be a fine line depending on the loss of arrow speed the formula i have for figuring KE is
arrow speed squared X arrow weight
divided buy 450,240
dose this sound right to you?
