Hello to the Martin world ! I quit bowhunting about 10 years ago, and still have my Firecat that is over 15 years old. Well, I decided to get back into bowhuntin' and I just bought a new 2012 Cougar FC Pro (60 lb limbs) with the Fury XT cam. Got the bow set up and tuned, and am looking forward to shooting and hunting for spring gobbler. Would the Grim Reaper 100 gr expandables be a good broadhead to lop off a gobblers head @ about 30 yards ? Or, would you recommend a fixed broadhead for head shots ?
