During the late 1950's and into the early 1960's the US Army Marksmanship Training Unit at Ft Benning, GA experimented with large capacity cases at long range targets. Eventually they selected a cartridge very close to the Ackley Improved 300 Magnum. The first cases were made from 300 H&H cases as were Ackley's cases. Remington then made some cases for this unit, but altered their headstamp. Finally Winchester got into making these special case specifically for the AMU too. Winchester-Western cases had the military headstamp W C C 60 on their magnum cases indicating 1960.

Both Remington and Winchester bolt action rifles were used and these cartridges were also used for 1000 yard matches in the early 1960's

I picked one up some years back in a group of odd cartridges...lucky find. Not quite as scarce here.
