EAST ALTON, Ill.- Two years ago, Winchester® Ammunition introduced the world to the Ballistics Calculator at Winchester.com. Now the program that made a breeze out of calculating shot placement is improved for iPhone and iPod Touch users.

The original version of the Winchester Ammunition Ballistics Calculator for the iPhone and iPod Touch allowed users to choose centerfire rifle ammunition and compare up to three different Winchester cartridges with easy-to-read, high-tech ballistic charts and graphs. You could customize shooting conditions by entering wind speed and outside temperature and adjusting zero marks for sighting in.

Now the ballistics calculator has been improved to also help users to discover aiming points, impact points and trajectories for rimfire, shotgun slug and handgun hunting ammunition - just in time for fall hunting season.

"Our customers were impressed with the original ballistics calculator for centerfire rifles, but they wanted more," said Brett Flaugher, Winchester Ammunition vice president of marketing and sales. "We listened to the great feedback we received and now the Ballistics Calculator is improved for millions of iPhone and iPod Touch users."
