The ballistic coefficient (BC) is a measure of a bullet’s ability to overcome air resistance during flight. It is a dimensionless number that represents the bullet’s resistance to changes in velocity due to air drag. The higher the ballistic coefficient, the less the bullet’s velocity will drop over a given distance.
To calculate the ballistic coefficient, you need to know the bullet’s weight, its diameter, and its form factor. The form factor is a measure of the bullet’s profile, which is determined by its length and the distribution of its weight.
Here is a simple formula to calculate the ballistic coefficient:
BC = (m / C) * (v^2 / (p * A))
where:
m = mass of the bullet (in kilograms)
C = drag coefficient of the bullet
v = velocity of the bullet (in meters per second)
p = air density (in kilograms per cubic meter)
A = cross-sectional area of the bullet (in square meters)
This formula is a simplified version and there are more complex equations and models that can be used to calculate the ballistic coefficient, School Analytics taking into account other factors such as atmospheric pressure, temperature, and altitude. However, for many practical purposes, this formula provides a good estimate of the ballistic coefficient.
