The 7x61mm Sharpe & Hart Magnum belted cartridge (7mm S&H Super) was developed by Philip B. Sharpe and Richard Hart in the 1950s and based on the .300 H&H Magnum case.In 1953 Sharpe travelled to Scandinavia and the outcome of this trip was that
Schultz & Larsen of Denmark chambered the cartridge in their bolt action rifles while Norma started to manufacture commercial ammunition according to the disigners specifications. But today the cartridge is a handloader's perspective. However they have a variety of bullets to choose from, and Hornady lists load data for the cartridge.

Usage & Ballistics

While the 7x61 S&H Magnum is a good cartridge, it was overshadowed in the United States by the pre-existing 7mm Weatherby Magnum. Never a popular cartridge in the U.S., when the 7 mm Remington Magnum cartridge was introduced it spelled the demise of the 7x61 S&H.
