How important is FOC to you guys that have been shooting a long time? Does it make a big difference in arrow performance?
Up until a few months ago, I hadn’t measured FOC on one of my arrows in close to 20 years. I was discussing moose hunting with someone and they asked about the specs of the arrow I shot through my bull. Since these were of the same basic arrow configuration I’d been using since 2001, I became curious and did some calculations. If memory serves, they weigh within a few grains of 500 (about 9gpp on my normal hunting bows), and with 20-grain Flightmate adapters and 125-grain heads, their FOC is somewhere around 12%.
To answer your original question: FOC is not of much importance to me. But if I were to hunt something larger and tougher than elk or moose, I may rethink that opinion.
