Ammo For Sale - Handgun Calibers

From Wikipedia, the free encyclopedia:
"The 7 mm STW (Shooting Times Westerner) began as a wildcat rifle
cartridge developed by Layne Simpson in 1979. It is an 8 mm
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. Remington Arms Company was one of
the first large ammunition companies to produce this cartridge in
1997, with others like Federal Cartridge Company, A-Square, and
Speer also carrying it. All mass-market US riflemakers now offer a
selection of production models chambered for the 7mm STW, which has
established a reputation as a fine long-range deer and medium game
rifle.
The only the commercial 7mm cartridge to have more power than the
7mm STW is the 7mm Remington Ultra Magnum.Dimensionally and ballistically, there are similarities between the 7mm STW and the
6mm cartridge based on the .375 H&H Magnum case necked down, known
as the .244 H&H Magnum."
