Sling Shooter vs. Mechanical Rest — Man vs. Machine

Can a human, with a sling, shoot as well as a mechanical rest? The answer is “yes” (at least once in a great while) IF that sling shooter can deliver a record-breaking performance. Here’s an interesting tale of man vs. machine from our archives…

The USAMU posed an interesting challenge — could one of their shooters match the performance of a mechanical rest? Who would win in this battle between man and machine? You might just be surprised. At 600 yards, with an AR-platform rifle, the results can be remarkably close, based on targets provided by the USAMU. When clamped in a test rig, a USAMU M16A2 produced a 200-18X group with handloads. The USAMU says this was “one of our better 20-shot groups at 600 yards, testing ammo from a machine rest”. Can a human do better?

Remarkably, a human soldier came very close to matching the group shot from the machine rest. The photo below shows a 20-shot group shot by a USAMU marksman with sling and iron sights, using USAMU-loaded ammunition. The score, 200-16X, was nearly the same. As you can see, the USAMU rifleman didn’t give up much to the machine rest, even at 600 yards!

In fairness, this was no ordinary human performance. The 200-16X score was a new National Record set in December, 1994. This was fired by PFC Coleman in an Interservice Match at Okeechobee, Florida. Brilliant Performance.
