Trajectory μCard - Constant Drop. Calculate a trajectory card from bullet, velocity, firearm and atmospheric parameters. Density is calculated using input density altitudes. Muzzle velocity is found by using linear interpolation between two velocities measured as a fuction of temperature. Explanation of termsDefine a coordinate system where y is the range variable, x and z are perpendicular to the trajectory where x is to the shooters right and z is up. Then rewrite the derivative d u / dt a = d u / dt = (d u / dy) (dy/dt) = - k (u - w)+ g. But dy/dt is just the velocity in the y direction (down range) written u y, thenThe classical equation to calculate gyroscopic stability is as follows. ( Sg S g) is the gyroscopic stability factor, and must be above 1.0 if the bullet is to remain stable. Sg = 8π ρairt2d5CMα A2 B S g = 8 π ρ a i r t 2 d 5 C M α A 2 B. The variables are as follows: The gyroscopic stability factor. A bullet is stable if Sg S g is over 1.0.The G7 Ballistic coefficient does a better job of predicting the trajectory of modern long ogive, boat tail bullets to longer ranges than the G1 standard, however, it is still not modeling the exact Cd value or shape and will result in errors. Utilizing the popular and well-designed JBM ballistics code, Table 1.JBM Ballistics has some C code on their website free for anyone to download and modify. As long as the person writing the code knows what they are doing and the code is free of bugs, any of the various commonly used methods will work. However, every serious engineer that I know of uses the Point Mass method or an extension of it.

Define a coordinate system where y is the range variable, x and z are perpendicular to the trajectory where x is to the shooters right and z is up. Then rewrite the derivative d u / dt a = d u / dt = (d u / dy) (dy/dt) = - k (u - w)+ g. But dy/dt is just the velocity in the y direction (down range) written u y, then
