With my newly finished selfbow, I plan on shooting some Doug Campbell damascus trade points that weight 190grs....so far it looks like about 60# spine is what I need for them.
The other points I want to shoot are 300gr. Woody Blackwell stone points.
Here's my question: being as the stones are so much heavier, any educated guess' on how much I would need to go up in spine?? 70#???
It's not like there's a 300gr FP availible(at least that I know of), and I don't want to shoot the head more than a couple times....I need to be close right off the bat.
keep in mind this is a far from center shot selfbow, that I draw a solid 28"...
Thanx
