Black Eagle Carnivore Arrow FOC Calculations, Recipe for new hunting arrows?

02/02/2025 – Taking some time and venturing to my local sportsman club, I took that time and tested my recipes listed above. I did only test H series arrows (1-6) because I desire to up front have 100 grains in my arrows. Below is my research after shooting.

Symptoms

  • 200gn tips – I sighted in my bow for 20 yards with this setup and was hitting accurately. There was no noticeable abnormalities in arrow flight. I am using this as a baseline.
  • 225gn tips – no abnormalities in arrow flight.
  • 225 Plus 15gn Sleeve tips – no noticeable abnormalities in arrow flight, but I did have one arrow (2 test arrows) have a nock high upon impact.
  • 250gn tips – Appears to have some noticeable arrow whipping. Are arrow vanes hitting my rest? Arrow impact was hitting nock right.
  • 275gn tips – Same issue as 250gn.
  • 300gn tips – these are very heavy and are symptomatic of 275gn arrows. However, after thinking while testing, I fear that it will be very difficult to find or even bolster my arrows with an extra 200gn in tips before any broadhead is attached. More over, maintainability. I do not want to get lost in weight insertion systems and consistently have to maintain them.

Potential Route causes

  • Investigate if vanes are contacting drop away rest and there is ample clearance between vanes and parts of bow.
  • Bareshaft tune arrows.
  • There is no reason at 56# draw weight why arrows are too stiff and showing nock right.

Addendum

Remember:

  • Nock high indicates
    • Incorrect arrow spine
    • Arrow release issues
    • Arrow contacting bow
    • Nock point too high
    • Grip issues
  • Nock Right indicates
    • Arrow is too stiff
    • Cam Lean
    • Nock too high
    • Fletching issues
  • Nock Left indicates
    • Arrow is too weak.
    • Excess point weight
