Ballistic coefficient formula
Proceedings - EDGE
The formula is - Weight of the Bullet (in grains) X Velocity (feet per second) X Velocity (feet per second) X .000002218 = FPE. It assumes that a full metal jacket bullet (non-expanding) will perform the same on game as a jacketed bullet (expanding) and will have the …

Notice that when the correlation coefficient is positive, the slope of the line of best fit is. ... Charlie is analyzing ballistic data where the x coordinate is the bullet. ... (the Pearson Product-Moment Correlation Coefficient), use the formula. To make the computations easier, break the formula into three parts: a. b.

The ballistic coefficient a variation is the inverse of this in some systems) is generally used to lump the mass, area, and coefficient of drag values together. It will vary, sometimes by a large factor. Several initiatives are examining the time-rate of change for this combined parameter without looking at the individual contributions.

Because the Reynolds number is used to calculate the drag coefficient, both inertial and viscous drag forces are represented in the drag coefficient. In practice, the inertial drag forces dominate the problem. Even for small bullets at very low (termination) velocities, the Reynolds number will be greater than 100, so the boundary layer is ...

Ballistic coefficient - Wikipedia
The performance factor is not the ballistic coefficient. It is simply a number which when divided into the velocity at a given distance will calculate what the velocity will be 10 yards farther downrange. ... In addition to accounting for both viewpoints, this formula has been crafted to yield a value which is equivalent to the weight of an ...
