I built it from gathering some information together and running it through JBM Ballistics. So what data do I need? First, you must know the bullet you're firing. In my case, that's a Lapua Center-X 40gr 22LR cartridge. Lapua lists the ballistic coefficient (BC) as a .172 G1. Second, you have to know your velocity.Ballistic Coefficient (Time) Calculate a ballistic coefficient from initial velocity, time of flight and distance.

May 18th, 2011 JBM-Powered Ballistics Software for Apple iPads. A dedicated iPad version of Ballistic ('Ballistic' App), a full-featured ballistics calculator for the iPhone, is available for the growing numbers of iPad users. As with the iPhone version, 'Ballistic' App for the iPad is "powered by JBM Ballistics" so it offers very precise solutions — typically, at 600 yards, JBM ... You can, but not very accurately. If you look at the bullet drop for two bullets, one with a BC of 0.5 and the other with a BC of 0.55, you'll find that the bullet drops at 300 yards with a muzzle velocity of 3000 f/s and a 100 yard zero, are -10.9" and -10.7" respectively. So if you can shoot groups less than 0.2" at 300 yards, have at it.

Ballistics are a complex interaction of factors including the load, rifle, altitude and weather. No one formula can do it all. Before you begin to think about either of these things, it would serve you well to learn to do range estimations with a pen and paper and use something like JBM ballistics (also discussed elsewhere) to build some ...

If checked, the windage is changed to make the bullet cross the line of sight at the zero range -- zero windage at the zero range. Wind Angle. The angle of the wind relative to downrange (0 degrees), 90 degrees is to the shooter's right, 180 is a head wind, and 270 degrees is to the shooter's left. Wind Speed 1, 2 or 3.The velocity at which the ballistic coefficient entered above is defined. If you only have one BC and no velocity information, use the average of the muzzle velocity and terminal velocity so that you get a new ballistic coefficient representative of the velocity range you are using.k 4 = h F ( x n + h, y n + k 3 ) The equations of motion for a bullet in flight, are simultaneous coupled differential equations. Specifically three equations for acceleration, position and spin. These equations may have been transformed using the substitution: d u /dt = d u /dy dy/dt = d u /dy u y.The world-renowned JBM Ballistics computer is now powering all of Ballistic’s computations. JBM is used by world-class shooters everywhere to deliver some of the …Changing Variables of Integration. From the discussion on CD and KD, we know that the acceleration of the bullet is. a = - k v + g. where. k = = p/p 0 G (m)/C. Rewrite the acceleration as a derivative. a = d u / dt = - k ( u - w) + g.

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.
