Not anything real scientific, I was gonna do more but ran out of time. Just thought some might find the results interesting. I'll probably play with it again later, but currently these were the only heads I played with.


I had a target set at 75 yards, labradar setup, tracking arrow velocity to the target. I can't confirm exactly what the ranges were that it was picking up on the velocity except what it says. It was tracking them at 11, 22, 33, 44, and 55 yards as well as at launch. I was just shooting 2 arrows at a time, had AAE Max Stealth vanes with 3 degree helical.

Shot field points(125gr), then IW wide 125gr, IW solid 125, Sevr 2.0 125, Field points again to check, then Day6 EvoX about 131 gr. 2 different heads of each shot, then just switched heads over for another 2 shots.


Summary:
From launch to 55 yards:
Fp's lost 27.5 fps
IW W125 lost 41 fps
IW S125 lost 35.5 fps
Sevr 2.0 lost 35.5 fps (tho a wider range)
Day6 EvoX lost 34.5 fps


I was surprised at the similar drop off with the Sevr and the fixed heads, also expected the large cutting EvoX to loose more than the smaller heads.

Chicken scratch data, because I'm not much on actual spreadsheets.

I also compared the AAE Max Stealth vane in 3 fletch 3 degree to Bohning Bronco at same specs and then Bohning Heat 3 fletch with 1 degree offset, losses were all within a few fps of each other. Speeds were different as weights were different, but degradation was 27.5-30 fps. Found that really surprising.

I find this useful. Though I am in the Primitive Bow Camp, and with no chronograph, I can extrapolate your data to see that my 44# bow might be a bit slow at 25 yards.
