I only have one thing to say, GRIMREAPERS!!!! I have taken over 43 animals, deer, bear, hogs and a Gold Series Catalina Ram and have NEVER lost one!!! They perform as they advertise, watch them drop!!!
I have had less than 5 animals travel over 75yds and never over 125 yds, less than ideal hits. They don't use rubberbands to hold them closed. They have a trocar tip that smashes bone like an ax.
They make a video that shows them using several brands of fixed and expandable heads shooting into plywood, steel drums, angle shots, etc... They all failed compared to the GR's. You won't go wrong.
