Total Drop at Target: — (Adjust your scope accordingly)

Best 22LR Ballistic Calculator Formula:

Drop (inches) = (0.5 * g * t²) – (SightHeight + (Range * tan(Angle)))
Velocity Decay: V_final = V_initial / (1 + (V_initial * k * x) / BC)

Variables Explained:

  • Muzzle Velocity: The speed of the bullet as it leaves the barrel (feet per second).
  • Bullet Weight: Mass of the projectile in grains (common 22LR is 40gr).
  • Ballistic Coefficient (BC): The bullet’s ability to overcome air resistance (G1 model).
  • Zero Range: The distance where your point of aim equals point of impact.
  • Sight Height: The distance between the center of the scope and the center of the bore.

What is the Best 22LR Ballistic Calculator?

The Best 22LR Ballistic Calculator is a specialized tool designed to account for the unique flight characteristics of rimfire ammunition. Since .22LR rounds are relatively slow and light, they are highly susceptible to gravity and wind, making accurate calculations essential for distances beyond 50 yards.

Professional shooters use these tools to determine “Holdovers.” By inputting the specific Ballistic Coefficient (BC) of their preferred ammo—such as CCI Standard Velocity or SK Rifle Match—they can predict exactly how many inches the bullet will drop at 100 or 200 yards.

How to Calculate 22LR Ballistics (Example):

  1. Determine your Muzzle Velocity (e.g., 1070 fps for subsonic rounds).
  2. Identify the Bullet Weight (typically 40 grains).
  3. Measure your Sight Height (standard scope rings are usually 1.5 inches).
  4. Input your Zero Range (the distance you sighted in at, usually 50 yards).
  5. Calculate the Time of Flight to the target to estimate gravitational pull.

Frequently Asked Questions (FAQ):

Is 22LR effective at 100 yards? Yes, but the bullet drop is significant (often 5-7 inches depending on zero).

What is a good BC for 22LR? Most 40gr lead round-nose bullets have a G1 BC between 0.110 and 0.150.

How does temperature affect 22LR? Colder air is denser, increasing drag and causing the bullet to drop faster.

Why use a ballistic calculator? It eliminates guesswork and saves ammunition by providing precise scope adjustments.
