How to measure group sizes using Ballistic for iOS

Ballistic is the definitive ballistics trajectory calculator for iOS devices, intended for serious shooters who want a serious (and seriously accurate) application. Ballistic calculates trajectory, windage, velocity, energy, and bullet flight time for any valid range, and can compensate for atmospheric conditions such as temperature, barometric pressure, humidity, and altitude (it can also accept density of air or density altitute input). It’s also much more than a basic trajectory calculator. With a vast library of over 4,000 projectiles and factory loads, Mil-Dot and MOA rangefinder with head-up display capabilities, GPS and atmosphere awareness, full size charts, reloading companion, precision target log, and optional HUD for mounted firing, Ballistic is a complete precision marksman tool for hunting, at the range, or at home with your hand loads.

The world renowned JBM Ballistics computer is powering all of Ballistic’s computations. JBM is used by world-class shooters everywhere to deliver some of the most precise calculations. This great ballistics computer is now available in the palm of your hand and simpler to use than ever, and because it’s fully integrated into Ballistic, you’ll even be able to take JBM’s extremely accurate calculations with you, even into areas with no cellular coverage.

This is almost cool enough to get an iPhone or iPad for. I mean, for serious shooters. Not at all for gadget fans. It’s called Ballistic, and it costs 20 bucks.

The iPad is a tool, not a toy, and when I take mine to bed with me, I’m getting work done. Don’t question that. It’s mine and I can scroll as fast as I want.
