Why Ballistics Matter

Ballistics refers to the science of projectile motion. Understanding ballistics helps shooters improve precision and make more informed decisions.

As a bullet travels:

• Gravity pulls it downward
• Air resistance slows it down
• Energy gradually decreases

Without proper ballistic calculations, shots over long distances can become inaccurate.

What This Calculator Measures

The 308 Ballistics Calculator provides three key ballistic measurements.

1. Bullet Drop

Bullet drop refers to how far the projectile falls below its original trajectory because of gravity.

Longer distances generally result in:

• Greater bullet drop
• More aiming adjustments

---

2. Velocity at Target

Velocity decreases as the bullet travels through the air due to drag and resistance.

Target velocity helps estimate:

• Projectile performance
• Penetration capability
• Impact effectiveness

---

3. Energy at Target

Impact energy measures the force delivered when the bullet reaches the target.

Higher energy often means:

• Greater stopping power
• Better penetration
• Improved terminal performance

How the 308 Ballistics Calculator Works

The calculator uses simplified ballistic formulas to estimate projectile behavior over distance.

Bullet Drop Formula

$\text{Bullet Drop} = \left(16.087 \times t^2\right) \times 12$Bullet Drop=(16.087×t2)×12

Velocity Decay Formula

$V_t = V_0 \times (0.998)^{\frac{d}{100}}$Vt​=V0​×(0.998)100d​

Energy Formula

$E = \frac{w \times v^2}{450240}$E=450240w×v2​

Where:

• $t$t = time of flight
• $V_0$V0​ = muzzle velocity
• $V_t$Vt​ = target velocity
• $d$d = distance
• $w$w = bullet weight
• $v$v = velocity

The calculator instantly processes these values and displays the estimated results.
