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.

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. To make it as accurate as possible, it is important that you input the most accurate information that represents shooting conditions, your firearm, and cartridge. The two most important variables are the Initial Velocity and the Ballistic Coefficient. If you do not have a Shooting Chronograph , I strongly suggest you purchase one. It is a great investment if you want to get into long range shooting and will be especially useful if you handload. I want this to be the best ballistic trajectory calculator out there.

Note that a ballistic coefficient of G1 Flat Base Ammunition or G7 Boat Tail Ammunition is ideal for traditional hunting and varmint bullets at close to moderate distance, sierra ballistics calculator.

Our free Ballistic Calculator generates thousands of shot simulations using your provided load, muzzle velocity, and real-world environmental conditions to create the most accurate bullet drop compensation data available. You're not currently signed in. You'll need to Sign In or create a Ballistix Account if you'd like save your calculation data. Start by entering your specific environmental factors and constraints as well as your ammunition and firearm details into the the calculator form. We also collect information about your rifle scope so we can provide you with compensation results specific to your scope's make and model.

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.

The description includes key features, modes of operation, and tables and graphs which the program provides. Features of Infinity. Infinity incorporates a number of significant features. We hope we have succeeded in making this information truly useful to you. The program has eight computational modes of operation, and it performs these operations on any one of five selectable active bullets at any time. In the first operation, the Trajectory computation operation, it computes downrange, vertical, and crossrange positions and downrange, vertical, and crossrange velocities in slant range coordinates referenced to the extended bore line of the gun. That is, it performs the trajectory computations for level or non-level shooting and refers the data to the direction in which the shooter is pointing the bore of the gun. It also computes time of flight, energy, momentum and wind deflections. It does these computations for specifiable atmospheric conditions, altitudes and wind conditions. This operation permits the selection of 10 different tabular printout formats.

Wind Speed: [? Thank you for your interest in Hornady. There could be an impact at the longer ranges due to the increased time of flight over the slightly longer flight path. Which drag function should I use and why? Plus you can save favorites, add notes and more. What is a Ballistic Coefficient? In the real world, projectiles do not travel in a straight line. The following figure illustrates drop when the line of departure is horizontal. Sight Height 0. Maximum Point Blank Range MPBR refers to the maximum range for which the firearm can be zeroed such that the bullet will neither rise above the line of sight farther than one-half the vital zone height nor fall below the line of sight more than one-half the vital zone height. The Time of Flight column shows the flight time to the range distance in the range column. Why Headwinds are More Difficult than Crosswinds. Altitude: [? Ballistic Coefficient 0. To use it, just pick a bullet from our library, fill in the appropriate information and click "Calculate".

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.

The next two lines of the header must be taken together in the discussion. 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. Drag Function: G1 Ballistic Coefficient: 0. Barometric Pressure: [? The figure below highlights the basic table elements. They provide an excellent introduction to advanced ballistics topics, but without all the tortuous math. You can measure this with a chronograph, or look it up in a reloading manual feet per second. Ballistic Resources Gain a deep knowledge of ballistic science and access our improved ballistic calculator. This creates the drop discussed later. At an Elevation Angle of: 0 degrees. The Velocity column is the speed with which the bullet is moving at any given point. Wind Heading The direction of the wind.
