Title: Arrow drop formula?
Post by: Boomerang on October 14, 2008, 12:24:00 PM

Hey guys,
Is there a formula to figure arrow drop? Lets say one bow shoots 180 fps. and another bow shoots 170 fps. what would be the difference in drop in arrow flight at 20 yards between the two?

Thanks,
Boomer

You guys think too much.....   :confused:

If you shoot the arrow and it hits the target,who cares?????

(and if you don't hit it,practice untill you do)

Seriously I think too many variables here to calculate accurately that drop....  Arrow weight, feather length/height, helical or offset. I'd recommend trial and error to figure it out.
