What Is FOC and How Does It Affect Arrow Flight?

While F.O.C is less relevant in some bowhunting situations (short-range shots), it can be critical in others (long-range shots, when shooting low-poundage bows and fixing trajectory issues at the range). It’s generally accepted among archery experts that a high F.O.C. will fly with good stability, but will shed its trajectory quicker and nose-dive. An arrow with low F.O.C. will hold its trajectory better, but can fly erratically. Easton recommends an arrow with 10-15% F.O.C. for hunting setups and optimal accuracy – especially at long distances…-Learn More at
