Here is my current setup:
Arrows cut to 29.75" from nock throat to BOP
ICS Bowhunter 500, wrap, nock and 3 x 4" feathers 260.00 gr.
Brass insert 100.0 gr.
Steel field point 145.00 gr.
Total Weight 505.00 gr.
52# @ 28" Kanati 58" R/D Longbow, gpp = 9.71
Balance point = 21.50
Percent FOC = 20.59%
Comments:
Shoots great groups out to 25 yards (as far as I could get in my driveway). Arrow flight was excellent, no wobble or porpoising.
I'll be using a 150 gr. broadhead (Woodsman Elite most likely). This will bring my total up to 510. The added length of the broadhead will likely mean little change in FOC or spine, but I'll test that theory when I get the broadheads.
I would think you could use almost the same setup for increased FOC without messing with your trajectory, just by cutting these arrows to closer to your length (be careful, carbons are stiff).
With a scary sharp broadhead, I would use this for anything I'm likely to hunt.
