so i've got my bow bare shaft tuned (I'm pretty sure). Any variances at this point are slight and I'm sure they are due to form.
i have the 65#-70# cedars cut to 30 inches with 125 grain points.
now my obsidians are around 90-110 grains. i don't want to "practice" with them...just hunt.
is there a standard best practice on how i should calculate the arrow length for the ones i will mount the obsidians on? in other words, how much should i lengthen from my known config that works. Ex. 1/2 inch per 10 grains....
maybe i am over thinking this and it really doesn't matter.
