The specs on my Mathews Jewel bow says IBO is up to 325 FPS with #60 bow @ 29 inches. My Jewel is set to approx. #56 and my draw is 26 inches. Is there a way to calculate approx. IBO with these details without a chrono?
Also, the specs on my APA Sidewinder says the IBO is up to 318, but I can’t...
LETS SEE WHAT YA'ALL GOT!
If you have Chrono photos or vids with your shot, even better.
Personally, I'm pretty thrilled with my setup, and would love to hear what others are getting. Please only post if you're above 330FPS on your current setup.
335 FPS :)

As far as I know IBO is the speed most bows are rated to and it is the arrows speed in fps with a 70# bow at 30 inch draw. If i have a 70# bow with say 27" draw (i don't just for example) couldn't your bow shoot faster than the advertised speed? Thanks!
