Ballistic Trajectory 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, 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.

shooting chronograph

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. Please let me know how it can be improved upon. You can find an email form and contact information here. Thank you.
