Sierra INFINITY Exterior Ballistic Computer Software version 7 (CD-ROM)

Sierra INFINITY Exterior Ballistic Computer Software version 7 is a Windows-based trajectory calculation platform designed for precision shooters, ballistics engineers, and long-range hunters who require accurate projectile performance data across variable conditions. This CD-ROM software computes detailed trajectory charts, graphics, and point-blank range solutions while accounting for uphill/downhill shooting angles, crosswind drift, and atmospheric variables that affect bullet flight.

The software delivers trajectory output in multiple formats—including minutes of angle (MOA) and milliradian (mil) increments—enabling shooters to generate load-specific drop tables for any firing condition. Maximum range calculations help establish the practical limits of a given load and rifle system, while custom bullet library functionality allows input of proprietary or handloaded projectile specifications.

This ballistic software serves precision rifle competitors, military and law enforcement training programs, ammunition developers, and serious long-range hunters who need repeatable, environment-specific trajectory data before field deployment. Revised print formats and improved atmospheric modeling in version 7 allow shooters to account for temperature, barometric pressure, humidity, and altitude—variables that can significantly affect shooting accuracy.
