Quick Answer
Changing broadhead type can indeed improve Front Of Center (FOC) balance, but it's essential to consider other factors like arrow weight, spine selection, and fletching to achieve optimal results.
Choosing the Right Broadhead
When selecting a broadhead, consider its weight and how it will affect your arrow’s balance. A heavier broadhead will shift the FOC forward, while a lighter one will move it backward. For example, the Rage X Expand broadhead weighs 125 grains, while the Slick Trick Stealth weighs 75 grains. If you’re using a 300-grain arrow, a heavier broadhead like the Rage X Expand will move the FOC forward by approximately 0.25 inches.
Understanding Arrow Spine and Weight
Arrow spine is critical in determining the FOC balance. If your arrow is too stiff, it may not flex enough, causing the broadhead to be too far forward. On the other hand, if the arrow is too weak, the FOC may be too far back. A good rule of thumb is to select an arrow with a spine rating that matches 80-90% of the arrow’s weight in grains. For a 300-grain arrow, a spine rating of 7/8" would be suitable. Additionally, arrow weight plays a significant role in FOC balance. A lighter arrow will require a heavier broadhead to achieve optimal balance, while a heavier arrow will require a lighter broadhead.
Fletching and FOC Balance
Fletching can also impact FOC balance. A wider fletching will shift the arrow’s center of gravity backward, while a narrower fletching will move it forward. Typically, a 3-inch wide fletching is considered optimal for most hunting applications. However, if you’re using a heavier broadhead, you may need to adjust the fletching width to achieve optimal FOC balance.
