When selecting arrow shafts for your bow, the materials you choose can significantly impact the FOC – Front of Center – of your arrows. Shafts made of lightweight materials, such as aluminum, carbon, and wood, will have higher FOC ratings than heavier materials, such as brass and stainless steel. A higher FOC will allow for a flatter arrow trajectory, improved accuracy, and greater penetration. However, heavier arrow shafts offer increased durability and are better suited for hunting. Ultimately, the choice of shaft material will depend on your individual needs and preferences.
