Thread: How many feet per second/ per pound of draw weight?

  1. #1

    How many feet per second/ per pound of draw weight?

    Wondering if any of the math folks on here have figured this up. If I shoot the same arrow, but I add pounds on my draw weight. How many feet per second would I gain per pound of draw weight that I add? Just curious. Thanks

    That sounds right - might be lower if the bow is on the low side of maximum draw weight. And conversely be higher if on the high end of draw weight.

    Meaning that: Dragmans 2.5 fps/lb. is a good average

    Does this means, if a bow ibo at 350 fps @ 70#, 350 gn. 30 dl, then a 60# will be around 325 fps? Perhaps a dumb question, but i'm kinda new to this :-D

    Yeah, it would be close.

    I usually figure what others have said, 2 fps/pound.

    So if you drop ten pounds you're looking somewhere in the neighbor hood of 20fps loss.

    Along the same lines, what do you lose for adding things lik peep, d loop, kisser, and arrow weight?
