The set-up was very similar to that pictured below. Wind conditions on the shooting range were continuously monitored using a Wind Probe. A mirage shade was attached to the objective-bell of the scope.
Sighting was accomplished via a Leupold VARI-X III set at 25X magnification and adjusted to be parallax-free at 100 yards. The free-float handguards of the rifle rested in a Sinclair Windage Benchrest, while the stock of the rifle rested in a Protektor bunny-ear rear bag. Pictures of shot-groups are posted for documentation.Īll shooting was conducted from a concrete bench-rest from a distance of 100 yards (confirmed with a laser rangefinder.) The barrel used in the evaluation was free-floated. Also, a control group was fired from the test-rifle used in the evaluation using match-grade, hand-loaded ammunition in order to demonstrate the capability of the barrel. As many of the significant variables as was practicable were controlled for. The shooting set-up will be described in detail below. fliers, target movement, Butterfly Shots). There was absolutely no use of any Group Reduction Techniques (e.g. This accuracy evaluation used statistically significant shot-group sizes and every single shot in a fired group was included in the measurements.
An accuracy (technically, precision) evaluation of the first-run MK262 Mod 1 ammunition was performed following my usual protocol. The specification for accuracy testing of MK262 calls for multiple 10-shot groups to be fired which is exactly what I like to do for a range report.
