Winchester has launched a new ballistics calculator app for the iPhone. It’s a good application for comparing different Winchester ammunition. There’s a good variety of loads and you can set the conditions such cross wind, temperature and the sight-in range you used. There’s also an online version that will allow you to print the data.
I played with Winchester‘s Ballistics calculator online for about a good hour, just having fun with all the different loads and learning the effects the conditions would have; however (to no surprise) it has only Winchester loads available. Its a great way to kill some time in the office. The iPhone app is free and available for download in the app store.
