Sierra ballistics calculator

Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, sierra ballistics calculator, windage, and velocity.

Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. It will a produce a line graph showing the bullet drop and flight path of the bullet. By adding trajectories to the panel on the right you may produce charts and graphs that show the different trajectories side by side. This can be useful in comparing cartridges or loads. Keep in mind this is an approximation and although it is quite accurate it should never replace first-hand experience of shooting your specific firearm and ammunition to determine the bullet drop and windage at different ranges and conditions.

The basic elements of a trajectory and the information contained in the tables are described below. We have included the most useful trajectory parameters velocity, energy, drop, bullet path, wind drift and point blank range with the zero range to maximize it in the Infinity tables. For each computed trajectory, they are tabulated for the user-selected muzzle velocity and shooting conditions. This discussion uses an example of a popular rifle bullet to discuss each element of the baseline table and explain the important terms. Trajectory: The trajectory of a projectile, in this case a rifle bullet, is the actual path that the projectile follows after leaving the muzzle. It is very important that this term be understood before using the tables. The trajectory of the bullet is shaped by many factors: gravity, altitude air pressure , temperature, humidity, muzzle velocity, wind conditions, and the ballistic coefficient of the bullet itself. Although all of these have been discussed in much more detail in previous sections, the major contributors will be redescribed here as they affect the example trajectory. The figure above illustrates the parts of a trajectory as they are discussed here and used in the tables. As soon as the bullet leaves the muzzle, gravity causes it to begin to fall away from its line of departure. This creates the drop discussed later. The line of departure is an imaginary line through the longitudinal centerline Bore Centerline of the bore and is the line upon which the bullet is launched. The significance of this line will be discussed as each element of the tables is discussed.

The two most important variables are the Initial Velocity and the Ballistic Coefficient. Chart Step Size: [? Chart Column Customization [?

The Bison Ballistics calculator is a modern ballistics calculator for sportsmen. To use it, just pick a bullet from our library, fill in the appropriate information and click "Calculate". Enter a BC and matching drag function, or select a bullet from the library and then enter the following variables:. Yellow text means the bullet has gone transonic, or under Mach 1. Red text means the bullet is subsonic, or under Mach 1.

Enter a BC and matching drag function, or select a bullet from the library and then enter the following variables:. Yellow text means the bullet has gone transonic, or under Mach 1. Red text means the bullet is subsonic, or under Mach 1. For the most stable and predictable flight, it is best to keep the bullet in the supersonic black text region. This is the result of the bore being lower than the scope's line of sight. At very short ranges say, 1 yard , it would require huge angular adjustments in order to get the scope pointed at where the bullet hits.

Bullet library includes all major bullet companies as well as ammunition companies and allows for addition of new and custom bullets. Both are retired Chief Scientists from a major aerospace company. This program is available in CD-Rom format only. Interface and program architecture design by Rodney Korn. The program does much more than compute bullet trajectories.

Muzzle velocity, air resistance ballistic coefficient , and gravity are the major contributors to trajectory shaping. When you're ready, click calculate to generate your custom ballistics chart. There is some information to be gained outside of the math as well, but this is really a college text book at its core. They provide an excellent introduction to advanced ballistics topics, but without all the tortuous math. The Velocity column is the speed with which the bullet is moving at any given point. In practice, the elevation angle is a small fraction of a degree. Sight Height: [? Relative Humidity The relative humidity in percent. The deflection of the bullet due to crosswind is related to the crosswind velocity or crosswind component of a wind from any direction and the time of flight of the bullet. It is a great investment if you want to get into long range shooting and will be especially useful if you handload.

The description includes key features, modes of operation, and tables and graphs which the program provides.

Wind Speed: [? Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. The deflection of the bullet due to crosswind is related to the crosswind velocity or crosswind component of a wind from any direction and the time of flight of the bullet. For almost every long range boat tail bullet, G7 is a better fit than G1. The concept applies equally well to the metallic silhouette and other games. Developed with in British Columbia. New Products Introducing the latest products from the worldwide leader in ammunition. The basic elements of a trajectory and the information contained in the tables are described below. The factor of converts bullet weight from grains to pounds The Kinetic Energy of the bullet can then be found from the formula:. The Altitude value is the altitude or elevation of the firing point above sea level, and the Temperature value is the temperature of the air at the firing point. On a prairie dog or ground squirrel the vital zone is much smaller, typically 2 to 4 inches in height. That means that the projectile is modeled as a point in space and affected by drag and gravity.
