History
Developed in 1960s by necking .284 Winchester to 6.5mm. Quickly became dominant in long-range competition. Swedish ammunition maker Norma began producing factory ammunition in 1990s. Never achieved full SAAMI standardization but widely used. Dominated 1000-yard competition until 6.5 Creedmoor's introduction. Offers more velocity than Creedmoor but requires long action. Still very popular in F-Class and long-range hunting.
