Your also shooting an arrow that is way too light for your bow Brandon and sooner or later you are going to detonate your limbs. Not a question of if but a question of when. If you do, Bow Tech will not warranty that bow if they figure out you been darn near dry firing that bow. 5 grains per pound is the rule of thumb that all bow makers recommend for any bow. That translates to a 350 grain arrow you should be shooting at a minimum. Good luck with that.
If your even close on your speed estimate, you are producing 78 ft lbs of kinetic energy at great peril to your bow. 1 pound more than I generate with an arrow nearly 100 grains heavier. You might want to re-think what your doing before its too late.
