Broadheads at distance, velocity lost.

Which setup are you saying is best?

I'm not and never will because best isn't a word that belongs in this discussion! We just didn't expect to see what we did.

makes total sense

What did you see?


I saw very little difference in fletching configurations, which was a pretty big surprise.

Very interesting! Glad you posted this. Precision Cut Archery and Easton seem to be doing a big arrow ballistic coefficient/drag/lift study right now (presumably to catalog all these different drag profiles and improve sight tape creation).

I’ll have to look up some downrange data I collected last year on the same arrow but fletched with Arizona Max Helical and Bitz 2deg offset/helical clamp. The data suggested there was not much difference which was surprising. Similar conclusion as what you posted above

I have another thread I did a few years ago, not on broadheads and fletching, but just on different arrow weights and retained speed at distance. I didn't have a labradar, might have been previous to them. I had a generator in a field with my chrono, a target, and was using a shooting machine to save my chrono.

The heavier arrows of course retained velocity better, but some of the lighter ones were going faster at 65 yards still than I think shafts 100 grs heavier were at launch, or something like that.

Maybe I'll find that post and link it here.

Not a lot of info, but some. Pretty common info with programs anymore. Post in thread 'Energy at range.' https://rokslide.com/forums/threads/energy-at-range.101187/post-981574

This stuff is pretty interesting to test out for yourself which is where I’m at. I did a downrange test with my “turkey” arrow using 4 fletch, lighter overall weight etc. I saw the same thing which is totally expected but still cool to prove

I’ll hear folks say that the heavier arrow will be faster downrange. But it’s a misunderstanding, instead they’re confusing deceleration with velocity, and within reason a lighter arrow will still be traveling at a higher velocity out to distance beyond normal hunting ranges (at least in what I saw in my test). The heavier arrow just loses velocity slower, again that’s obvious to many, but fun to tinker and see in backyard diy testing
