I was having a hard time tuning my 46#@27 58" whip. I tried 4 different spines of arrows only to settle on a .600 spined cut to 29.25.
With 175 up front I was getting good bareshaft flight. The bareshafts had wraps on them too. So i finally put feathers on them and the arrows seemed to be squirrely in flight. Kind of corkscrewing. I added another 75 grains up front which seemed like overkill to me but gave me perfect fletched flight. They fly dead straight and hit hard. Logic says these should be weak but they fly good. Anyone else ever experience something similar?
Good flight bareshafting but squirrely with fletching. Maybe a contact issue.
600 spine with 175+ up front seems like it would be a little weak.
I shoot 600 gt trads 28" 100 gr. inserts with 150 gr. grizzly heads. My bow is 45# at 26" maddog prairie R/d at 56" .
You were probably borderline stiff before and the addition of feathers stiffened you even more and adding the 75gr got you in the sweet zone
