Buckkilla,I use the 125 grain rocket steelheads.Don' t worry about what they will do to a deer.Have killed 5 deer with them all pass threws,I deer was quartering away.I am shooting 70 lbs out of a mathews MQ32 so we are shooting similar speeds.Most important part of bow hunting is arrow placement if you shoot these well rest assured when you get your opportunity on a deer they will preform.My bow is tuned and It is difficult to get good fixed blade flight.Good Luck
