Motion of the muzzle of a shoulder-fired weapon occurs during firing because of many factors, such as breathing, trigger pull, and flinching, and can also be introduced as a result of offhand shooting in less than stable shooting positions. This motion can have adverse effects on the capability of the weapon to hit a target because the shooter is unable to accurately position the muzzle of the weapon onto the target as the projectile exits the barrel. Electronic fire control offers the opportunity to extend the range and accuracy that can be achieved by a sniper or a long-range shooter with the implementation of a dynamic ballistic solution and a precise firing time selection. The Inertial Reticle Technology IRT has been developed at the U.S. Army Research Laboratory ARL as a novel solution to fire control for such applications. Therefore, to improve the accuracy of a shoulder-fired weapon, ARL applied the IRT to a rifle. This report presents the complete details of how the IRT was applied to a Remington 700 sniper rifle, along with analysis of long-range live-fire test data fired by a test engineer and an Army sniper.
