You'll have to know the arrow weight in order to get the kinetic energy. The formula for kinetic enrgy is velocity squared times mass, then divide that number by 450240. For example I'll give you mine. [(230*230)*382]/450240=44.9

I hope this helps you out.

Hoyt108, If youa re getting 61 lbs then that is plenty for pretty much anything in North America. For whitetail deer, I think around 35 is sufficient.

Yes sir, you'll have more than enough KE for a mech b-head. You should have very similar KE levels as I do and I've been using Rockets with excellent results. I would suggest that you keep your choices to less than a 1 3/4" cutting diameter unless you bump up your KE a bit. Good luck and good shootin'

well 61lbs. of KE might not be right i just guessed my arrow weight at 330 grains so I don't know if it is right. I guess I will have to go to the sporting goods store and get them weighed. Cause 61lbs. sounds like alot.
