Results

Bullet Drop at 0 yards: 0.00 inches

Windage Adjustment: 0.00 inches

Kinetic Energy: 0 ft-lbs

How to Use the Ballistics Calculator

  1. Enter Bullet Weight (in grains, e.g., 150gr for .308 Winchester).
  2. Input Muzzle Velocity (feet per second, found on ammo boxes or manufacturer specs).
  3. Set Zero Distance (yards/meters where your scope is calibrated).
  4. Add Wind Speed (mph/kph for windage adjustment).

Hit “Calculate” to see your bullet’s drop, kinetic energy, and full trajectory graph.

FAQs: Ammo Ballistics Calculator

How accurate is this ballistics calculator?

Our tool uses industry-standard projectile motion equations and accounts for gravity, wind drift, and velocity. For extreme precision (1,000+ yards), factors like air density and bullet BC (ballistic coefficient) become critical.

What’s the difference between bullet drop and windage?

Bullet drop is the effect of gravity pulling your bullet downward over distance. Windage refers to horizontal deflection caused by crosswinds. Both are calculated in our tool.

Pro Tip from Our Gunsmiths

“Always verify calculations at the range. Start with our tool’s estimates, then fine-tune based on real-world conditions like humidity and altitude. Learn how to level your scope.
