Grim Reaper WS and KE ?

[croc2116]

Do I have enough power (KE ft lbs) to shoot Grim Reaper Whitetail specials 2" cutting diameter? My setup is 390 grain arrows including 100 grain head, 27.5" draw length, 65 lb draw weight and an guess of 280 ft/ sec arrow speed. My bows maximum poundage is 70 lbs draw weight and 330ft/sec IBO speed.

Thanks

If you go through the ribcage... it don't take much. Sorry I can't help with more physics than that...
