Ballistic-X is the easiest way to calculate shot groups and to zero a rifle! Designed by shooters, the simple and intuitive interface allows user to setup their own preferences via our Options Menu. Options includes MOA/MIL, INCH/CM, and will work with any target, including Steel. BX also offers useful data and labeling options that aid in Load Development. Our ATZ (Adjustment To Zero) feature tells shooter precisely how to adjust turrets to bring rifle to Zero, allowing a perfect zero with fewer rounds shot. ATZ works dynamically at any range and is compatible with all turret options! Workflow is simple: - Take image of Target (within App or from Library) - Designate reference size via Settings (default is 1”) - Mark the two points on target which coincide with reference (grid target or steel target). The distance between the two points is reference size. - Input distance from Target - Select the Caliber used - Mark Point Of Aim and Impacts - Add Overlay, Label, Crop, and Export / Share - Adjust Optic according to ATZ Ballistic-X is a community driven App committed to the best user experience possible along with customer service second to none!
