7mm Shooting Times Westerner

The 7mm Shooting Times Westerner, sometimes referred to as the 7mm STW began as a wildcat rifle cartridge developed by Layne Simpson in 1979.[2] It is an 8mm Remington Magnum case that has been “necked down” (narrowing the case opening) by 1 mm to accept 7 mm (.284 in) bullets. This cartridge is named after the magazine Shooting Times where Layne Simpson is a regular contributor.

The 7mm STW graduated to commercial status when it was officially recognized by SAAMI in 1996.[3] Remington Arms Company was one of the first large ammunition companies to produce this cartridge in 1997, with others likeFederal Cartridge Company, A-Square, and Speer also carrying it. Many US riflemakers now offer a selection of production models chambered for the 7mm STW, which has established a reputation as a fine long-range elk and large game rifle.
