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.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 distance from the point of the first velocity measurement to the point of the second measurement. This is the distance between the two chronographs. Drag function. A drag function (or G function) provides the forces on a standard bullet for which the drag function was derived. A bullet's ballistic coefficient then relates the drag on any ...That wasn't what I see when I run the numbers on JBM ballistics. It looks like the 69gr bullets at 2850fps goes sub-sonic betwixt 700 & 800 yards on the JBM website. I have shot the 69's and the 77's both at 600yds and there is a very noticible difference in how they act in the wind though I've shot some good scores at 600yds with the 69's.Ballistic Coefficient The ballistic coefficient for the bullet being used. It is almost always obtained from the manufacturer, but can also be measured. The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting.Calculate a ballistic coefficient from initial velocity, time of flight and distance. Calculuated ballistic coefficient is displayed for selected drag function. Explanation of termsSince w x is constant, one can readily perform the integrals (assuming constant k) . u x = w x [ 1 - u y /u x0] . Integrate one more time with respect to t on the interval [0,t] x = ∫ u x dt [0,t] = w x [ t - R/u x0] . where R = ∫ u y dt [0,t] . and x is the deflection, u x0 is the muzzle velocity (initial velocity in the y direction), R is the range, t is the time of flight to that range ...August 1st, 2013 Updated URLs for JBM Online Ballistics Program.

Ballistic Coefficient The calculated ballistic coefficient for the selected drag function. Atmospheric Density The calculated density of the air. Speed of Sound The calculated speed of sound. Time The calculated time of flight of the bullet over the entered distance.The ballistic coefficient is represents the ratio of the drag of the standard (e.g. G1 standard bullet) bullet to that of the bullet you are shooting. A ballistic coefficient of 0.100 means that your bullet has 10 times the drag of the standard bullet. Barrel Twist The twist length of the barrel. Twist DirectionBison Ballistics bullets are all hand made. Every core is hand-swaged and weight-sorted prior to seating and point up. What this means is that not every lot will be exactly at the target weight. If the bullet's nominal weight is 200 grains, you might find one lot that weighs 200.1 and another lot that weighs 199.9.Kinetic energy is a function of the bullet mass and motion. This motion involves the velocity and rotations. It is represented by the following equation. KE = 1/2 M v 2 + 1/2 I w 2. NOTE: this assumes a single rotational axis and forward motion of the bullet. For multiple rotations and non-symmetric bodies, things get a little more complicated.The BC, or ballistic coefficient is defined as: BC = w / [i d 2] here the diameter is specified in inches and the weight in pounds and the form factor is found using: i = CD / CD G. The sectional density is defined as: SD = w / d 2. making the ballistic coefficient BC = SD / i

For two equations, dy/dx = F(x, y, z) and dz/dx = G(x, y, z), a single integration step of h is defined by:A bullet is stable if: Sg >. 1 Sd (2-Sd) If you plot that on a graph, you wind up with the following chart: As you can see, there are two regions divided by the line represented by the above equation. If a bullet is inside the stable region, all is good.
