Im really happy people are finally getting the word on Dr. Ed! Great job J

Every time a video on Dr. Ashby is posted, Ranch Fairy giggles with excitement.

I was raised shooting trad and have always built my arrows on the philosophy of at least ten grains of arrow for every one pound of draw weight. In 07, when I got my first compound, I fell into the speed trap for a couple of years, having had some success. Until I had a doe at 18 yards quarter towards. At that time, I was shooting a 458 grain arrow (edit: and 100 grain Montec) out of a 70#/29" bow. I hit her right where the bottom of the scapula meets the humerus. Stopping the arrow dead in its tracks from entering her vitals. I tracked her that night and the following morning, concluding she had survived. After that and talking with my father, I went back to building my arrows the way I original learned. This season, I am shooting 672 grains w/ 23% FOC out of my recurve and 920 grains w/ 28% FOC out of my compound (edit: 300 grain single bevel for both the recurve and compound)

I'm a big fan of Dr. Ed Ashby. I read his studies a few decades ago and began using Grizzly broadheads because of that. (At the time I reasoned that if the 190 gr Grizzly was good for huge animals, the 125 gr would be good enough for whitetails.). For some reason, I overlooked the bevel/feather relationship and shot right bevel left feathers. I still had amazing results and one humerus shatter/rib breach heart shot antelope in the mix. I've tried many good broadheads and have gotten good results with many, but I'm currently going with grizzly heads of various weights, but none less than 225 gr. The new FOC info has me shooting carbon with heavy tips. (25-28 % FOC)

Wow! Excellent supplement to your previous video on hunting arrows!

This may have been understood but not documented very publicly very early on. My boss, an old Detroit Archer worked at the Packard engine plant in Detroit during WW2. He casually noted one day that they would drive the tank armor developers crazy by sticking arrows in prototype armor! Take that as you see fit, but it is firsthand. Bows from that era were considered amazing if they could develop 200fps. So, the arrows they used to drive the armor developers nuts had to be constructed with components similar to the examples in the Ashby study. Two things that may have been able to do that were compressed wood shafts and something like the Delta broadhead. They may have also used the compressed wood shaft material loaded into an aluminum arrow shaft which would deliver the ultimate penetration from a bow of around 60# draw weight. I was also completely impressed by the reported successful broadheads since they had a lot in common with the tools in use at the onset of bow hunting post war. Check out some old archery magazines from the late 50's through the pre-compound era and note the designs.

What was the poundage of the bow to do the study? Just curious because a lot of guys like myself are shooting 45-50#. So a 650gr arrow is extremely heavy for #45.
