Coo Video Mr. Lusk... Thanks for sharing.
The most valuable takeaway for me from your testing demonstrates very clearly what I have seen time and again which is the Achilles heel of broadheads with aluminum ferrules. I have unfortunately experienced it myself with my own live experimentation with different style broadheads in Africa over the years, and I have witnessed similar failures more times than I care to remember with clients using broadheads with aluminum components....
You can get by with aluminum with some species up to certain body mass, but we recommend overall that our clients use a heavy-duty broadhead that is comprised of all steel. This is mandatory for large as well as dangerous game, but I still personally recommend all steel for plainsgame as well....
