So.....it would be a fairly safe bet that my Excalibur Vortex 330 is shooting close to 295 fps with a 455 grain arrow. (455-350=105/3=35...330-35= 295 fps)
And my CP Sniper 370 is close to 342 fps with the same weight arrow. (455-370= 85/3=28.33...370-28= 342
And my CP Patriot 425 is close to 397 fps with the same weight arrow. (425-370= 55/3=28.33...425-28=397 fps)
