I' m shooting 241 fps @ 67# and a 463 gr arrow. My KE Calculates at 60 ft-lbs and it has done the job every time for me. It is not the resultant of my mass or speed . . . the laws of physics prove that it is a product of the two. If one only considers speed he only has HALF of the equation. You simply cannot have one without the other and still be effective . . . and that is a law of physics that cannot be avoided.

Speed is not what kills! Mass is not what kills! It is and always will be the product of the two that provides penetration.

By the way Kriskin, your arrow would be ILLEGAL here in Washington State. You must have 6 grains of arrow per pound of draw weight.
