Precision Ballistic

Opens with live wind, temperature and pressure for where you stand, and tells you how many clicks to dial or which bar to hold.

Precision Ballistic is a rifle ballistics calculator for hunters and shooters. Range, wind, power and the answer all fit on one screen.

• Live weather: wind, gusts, temperature and pressure for your location, refreshed every 5 minutes; or pick a place, or enter your own. • Compass bearing: point the phone downrange and the app works out the wind clock; or choose the clock position yourself. • Plain answers: elevation and windage as angles and turret clicks, with the hold marked right on your reticle. • Reticle holds: built-in Swarovski, Vortex and Leupold reticles, first and second focal plane with power scaling; export a white range card to print and tape to your rifle. • Trajectory table: elevation, drop, windage, drift, velocity and energy by distance, with the transonic zone grayed out. • Truing: derive muzzle velocity and BC from your real impacts. • Ammo presets: popular factory loads and component bullets such as Sierra. • English and Chinese, with imperial/metric units set per item.

Results are for reference only and must be confirmed with live fire. You are responsible for safety and must follow local laws and hunting regulations. Weather data: Open-Meteo.com (CC BY 4.0).
