1. What is the Stopping Power Formula?

The Stopping Power formula, also known as the Taylor KO Factor, is a ballistic calculation used to compare the stopping power of different ammunition types. It provides a dimensionless value that helps evaluate the effectiveness of projectiles.

2. How Does the Calculator Work?

The calculator uses the Stopping Power formula:

Where:

• \( M \) — Mass of the projectile (grains)
• \( V \) — Velocity of the projectile (ft/s)
• \( D \) — Diameter of the projectile (inches)

Explanation: The formula calculates a dimensionless value that represents the relative stopping power of a projectile, with higher values indicating greater stopping effectiveness.

3. Importance of Stopping Power Calculation

Details: Accurate stopping power estimation is crucial for ammunition selection, ballistic comparison, and understanding the effectiveness of different projectile configurations for various applications.

4. Using the Calculator

Tips: Enter mass in grains, velocity in feet per second, and diameter in inches. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the 7000 divisor?
A: The 7000 factor is a scaling constant that converts the product of mass, velocity, and diameter into a dimensionless value for comparative purposes.

Q2: How does stopping power relate to actual performance?
A: While stopping power provides a useful comparative metric, actual performance depends on multiple factors including shot placement, target composition, and projectile design.

Q3: What are typical stopping power values?
A: Values vary widely depending on ammunition type. Handgun rounds typically range from 5-25, while rifle rounds can exceed 50.

Q4: Are there limitations to this formula?
A: The formula doesn't account for projectile expansion, energy transfer efficiency, or other ballistic factors that affect real-world performance.

Q5: Can this be used for all types of ammunition?
A: The formula works best for comparing similar types of ammunition. Specialized projectiles may require additional considerations.
