1. What is Arrow Weight and FOC?

Arrow Weight is the total mass of all arrow components measured in grains. FOC (Front of Center) is the percentage of the arrow's total weight that is located in the front half of the arrow. Both are critical factors in arrow performance.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( L \) — Arrow length (inches)
• \( AMO \) — Balance point from nock end (inches)
• All weights are in grains

Explanation: The FOC formula calculates what percentage of the arrow's weight is forward of the center point.

3. Importance of Arrow Weight and FOC

Details: Proper arrow weight affects kinetic energy and penetration. FOC affects arrow flight stability - higher FOC arrows fly more steadily but may drop faster.

4. Using the Calculator

Tips: Measure arrow length precisely from nock groove to end of point. Measure balance point from nock end to where arrow balances. Weigh all components accurately.

5. Frequently Asked Questions (FAQ)

Q1: What is a good FOC percentage?
A: Typically 10-15% for target shooting, 12-20% for hunting. Higher FOC improves penetration but reduces speed.

Q2: How does arrow weight affect performance?
A: Heavier arrows penetrate better but shoot slower. Lighter arrows fly faster but may lack kinetic energy.

Q3: What's the ideal arrow weight?
A: Depends on bow setup and purpose. Target arrows typically 350-500 grains, hunting arrows 400-600 grains.

Q4: How do I adjust FOC?
A: Add weight to point (increases FOC) or nock end (decreases FOC). Changing arrow length also affects FOC.

Q5: Why use Gold Tip arrows?
A: Gold Tip arrows are known for their consistency, durability, and precision engineering.
