FAIR WARNING BEFORE READING!!!!
I have not killed an animal yet with these broadheads.
They are extremely accurate, durable, and resharpen well from practicing on targets. I have been using them for over a year now with Easton Axis 5mm, 3 vane helical, and the Easton brass inserts were broken off at 50 grams. I only wish that they came with one dull practice head.
Cam Hanes uses them so why wouldn't we ;)
