I will let you fellas do the math as I do not know what the grain wt. is but I shoot a 30 inch easton aluminum 2419 with a 190 grain simmons broadhead. It is heavy and slow but in the thickets, my average shot is abot 10 - 15 yds sospeed is not much of a factor.

You will probably need new arrows. I also use 5 inch feather fletch from the primary wing feathers of the turkeys that I have killed. I know many fellows that shoot carbon but rarely is it the same set up as their compound bows.
