Ballistic Coefficient (Time) Calculate a ballistic coefficient from initial velocity, time of flight and distance. Calculuated ballistic coefficient is displayed for selected drag function. Explanation of terms. Near Velocity (500.0 to 4800.0 ft/s) [3000.0] [?] 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 terms. In spirit of giving gifts :) Top row is the wind direction with 90deg being a full value wind Left column is wind speed in mph. sight corrections are to the nearest 1/4 moa. Wind drift based on JBM Ballistics software.Ballistics calculations and formulas for small arms. Drag/Twist. Calculate drag and stability from bullet dimensions, weight, specific gravity and barrel twist.

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.

Ballistics calculations and formulas for small arms. Trajectory (Simplified) Calculate a trajectory from bullet, velocity, firearm and atmospheric parameters.

The drag function to use to calculate the ballistic coefficients. Most commercial bullets use the G1, but for some long range bullets, the G7 or G8 is typically a better choice. Some military bullets fit the G5 and G6 functions better than the G1.Since 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 ...On AccurateShooter.com's Ballistics Page, you'll find the excellent JBM Ballistics program. This not only calculates bullet trajectory with great precision, but will also output clicks so you can create your own "come-up" chart to keep with your rifle. In addition, you can download FREE versions of Pejsa and Point Blank ballistics ...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 ...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 Direction

Sort by Oldest firstThe 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 / iBoth Winchester and JBM ballistics have fairly comprehensive libraries with all of this information included with particular Winchester cartridges or bullets in the case of JBM Ballistics. The final piece of information you'll need is the height of the center line of your scope over the rifle bore. In most modern firearms this ranges from ...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.Ballistic’s world renowned JBM ballistics engine delivers the gold standard in calculations that other applications compare themselves to.
