60" 45#@28" (but i pull 25"). what weight am i really hitting?
Probably around 37-38#. Usually you can use 2 1/2# per inch but that can vary bow to bow and depending on your draw curve on your bow.
I draw that length and usually find about 9 pounds lower on a bow marked at 28". So I would guess 36#.
On a bow that's pretty light to begin with, you're only going to lose 2 -2 1/2# per inch of draw. I agree with ks, about 38#.
I would say 5% per inch. That equalls 6.75 lbs. So you are probably around the 38 lbs.
