1. What is the Taylor KO Factor?

Definition: The Taylor KO Factor is a dimensionless number used to estimate the stopping power of rifle bullets on large game.

Purpose: It helps hunters and ballisticians compare the relative effectiveness of different cartridges for hunting purposes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( TKO \) — Taylor Knockout Factor (dimensionless)
• \( m \) — Bullet mass (kg)
• \( v \) — Velocity (m/s)
• \( d \) — Bullet diameter (m)

Explanation: The formula combines bullet mass, velocity and diameter into a single number that correlates with stopping power.

3. Importance of Taylor KO Factor

Details: Higher TKO values indicate greater stopping power, which is particularly important when hunting large or dangerous game.

4. Using the Calculator

Tips: Enter bullet mass in kg, velocity in meters per second, and bullet diameter in meters. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's a good TKO value for deer hunting?
A: Typically 10-15 is adequate for deer, while larger game like elk may require 15-20.

Q2: How does this compare to other stopping power formulas?
A: The Taylor KO is simpler than some formulas but has proven effective for comparing rifle cartridges.

Q3: Should I use bullet weight or mass?
A: This calculator uses mass in kg. To convert from grains: 1 kg = 15432.3584 grains.

Q4: How does bullet construction affect TKO?
A: The formula doesn't account for bullet construction - it assumes proper penetration and expansion.

Q5: What's the range of typical TKO values?
A: Common hunting cartridges range from about 10 (small calibers) to 40+ (large bore rifles).
