I’ve been listening to the stickbow chronicles, and the Kifaru podcast a lot lately and decided to start figuring out what arrow setup will shoot perfectly with my longbow. Using the 3 Rivers Archery arrow spine calculator I found that I can get really close with the arrows I already have, with a different point weight. It just so happens I have some Carbon Express Heritage 150 arrows cut to 29.325 already and it’s just a matter of getting some heavier (way heavier) points. The calculator showed that switching to 250 grain points, I’ll be within roughly 2lbs of my bows dynamic spine rating, and from there I can play around with brace height to get them flying perfect. I’ve got 250 grain field points on the way, and I’ve already figured out how to get some zwickey broadheads that heavy too. Down the rabbit hole I go........ I never would have thought primitive, traditional archery could get so technical. It’s crazy!
