The weapon designs being tested will be “unconventional,” officials said, and likely not one that is currently commercially available.
Some intermediate calibers being tested include the .260 Remington, 6.5 Creedmoor, .264 USA as well as other non-commercial intermediate calibers, including cased telescoped ammo, Army officials said.
„Unconventional design“ often ends up meaning „weird, maintenance-intensive, and expensive“. Or, „something really interesting and promising that gets fucked up during the acquisition process,“ such as we noted here.
But, it’d be nice to see it go the other way!
