I just finished making a cane arrow for stumping/ small game. The cane is from 3Rivers. I added a hardwood internal footing and use a .30/30 case for the head. Real turkey feather 2 fletch, a self nock, and artificial sinew are used. I have no idea of the spine (I'd guess around 65), but the finished arrow weighed 540 grains.
Out of my BBO (55#@30"), it hits right where I look. I'll have to trim the feathers, though. They're pretty loud.
I'll make the next one a little longer and a little cleaner. My sinew wraps look a little sloppy.
