The online Winchester Ballistics Calculator measures trajectory. The ballistics charts and graphs also deliver detailed information including a visual representation of point of impact, flight time, drop, drift velocity and energy.
Using the ballistics calculator begins with choosing a type of ammunition from six categories that include shotgun slug, rimfire, centerfire handgun and centerfire rifle ammo. Customizing shooting conditions in the ballistics calculator requires entering wind speed and the outdoor temperature.
The Winchester Ballistics Calculator is accessible at BallisticsCalculator.Winchester.com. Utilizing the features of the online ballistics calculator, Winchester offers a user-friendly app for the iPhone as a free download from the Apple App Store, as of May 2015.
