History: Introduced in 1965 for the Remington Model 600 carbine — a short-barreled, lightweight bolt-action. The combination of a compact rifle and powerful cartridge was ahead of its time. The Model 600 was discontinued but the cartridge survived; the Ruger Model 77 later became its most notable platform. Factory ammunition availability has been inconsistent.
Notable firearms: Remington Model 600, Ruger Model 77
