How to Use This Calculator
  1. Enter Muzzle Velocity, Ballistic Coefficient (G1), and Range.
  2. Review the Time of Flight (s) result.
  3. Use Vacuum TOF (no drag) (s) and Lag Time (drag effect) (s) to inform your decision.
  4. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Range

RangeTime of Flight

1,8032.42 s

What each input means

Muzzle Velocity
Bullet muzzle velocity.
Ballistic Coefficient (G1)
G1 ballistic coefficient.
Range
Distance to target in yards.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Muzzle Velocity = 2750, Ballistic Coefficient (G1) = 0.45, Range = 500 = 3 input(s) provided
  2. Calculate Time of Flight
    Time of Flight = t
    0.5808 = 0.5808
  3. Calculate Vacuum TOF
    Vacuum TOF
    0.5455 = 0.5455
  4. Calculate Lag Time
    Lag Time
    0.0354 = 0.0354
