Hello Munsterman, and welcome to the forum. Dr. Ashby pops in from time to time so maybe he can help you find exactly what you are looking for.
At the top of this forum is a thread called Links to Ashby Reports. There you will find links to all of the studies and related material. One link, TBM Articles gives a listing of those that were published in Traditional Bowhunter. These articles are available to all members to be read on the site, but not downloaded.
I thought there was a summary but when I peeked briefly I couldn’t find it. Perhaps as you browse through them it will pop up. Let me know if you have any questions or problems with the files.
