“Excellent info, thanks.” [redfreedom, post 69]
Thanks yourself.
Much of this information has appeared in the print periodicals _American Rifleman_, _Small Arms Review_ or its predecessor periodical _Machine Gun News_, over the past 25 years or so. Some of the data on SCHV came from the most recent article sticking in memory, which appeared in the _Rifleman_ some three years back.
Most of that piece addressed Winchester’s “Lightweight Rifle,” their SCHV candidate which strongly recalled the M1 Carbine, made along very traditional lines out of walnut and steel. Despite solid manufacturing, it failed to meet accuracy/precision criteria and they withdrew from the program, grousing (in internal company communications) that a “new breed” of Ordnance officers had come on the scene, enamored of plastics and light alloys.
Perhaps the most interesting information in the article concerned Soviet research into small-caliber cartridges. Designers and engineers in the USSR began experimenting in the late 1950s, not long after US Army Ordnance initiated SCHV; their work was not in response to field observation of US systems in action in Southeast Asia. It ultimately led to the adoption in the 1970s of 5.45x39mm as the standard Red Army small arms round.
