Supplemental Reports
“You should spare neither effort nor expense in achieving perfect arrow flight. Even with every other factor in place, without good arrow flight you will have poor arrow performance” -Dr. Ed Ashby
The supplemental reports provide a solid exclamation mark behind all of the work Dr. Ed Ashby has provided in his detailed research and reporting. This information cuts through the marketing hype of “lighter and faster”. Target archery is very different than bowhunting and taking an animal’s life. We owe it to every animal we hunt to harvest that animal in an ethical way. It begins with a structurally secure, perfect flying arrow and broadhead combination of sufficient weight and forward of center weighting.
June 2022 case study by ABF and Strang Middleton of twenty-two popular broadheads tested on Cape Buffalo in Zambia. Critical factors were reviewed with each broadhead receiving an overall grade based on ten of the twelve penetration enhancing factors.

July 2021 case study by ABF and PHASA representatives of ten popular two-blade broadheads tested on Cape Buffalo in South Africa. The test was performed to see what the Cape Buffalo did to the broadhead - not what the broadhead did to the Cape Buffalo.

I‘ve spent 32 years in the United States Department of Defense scientific community, working in applied aerodynamics and ballistics. In this presentation I hope to provide underlying principles and insights of arrow flight that you can use to make smart decisions about your bow hunting equipment. Darrel Barnette
This paper reviews the scientific support for a ballistic pressure wave radiating outward from a penetrating projectile and causing injury and incapacitation. This phenomenon is known colloquially as “hydrostatic shock”, and no arrow comes anywhere close to generating the roughly 500 ft-lbs/700 joules of energy transfer required as a minimum, to produce hydrostatic shock. The idea originates with Col. Frank Chamberlin, a World War II trauma surgeon and wound ballistics researcher. Michael Courtney, Amy Courtney
