The 7x61mm Sharpe & Hart Magnum belted cartridge (7mm S&H Super) was developed by Philip B. Sharpe and Richard (Dick) 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. One example being the model 54J, which featured rear locking lugs and a fully enclosed bolt face. while Norma started to manufacture commercial ammunition according to the designers specifications. But today the cartridge requires hand-loading. However hand-loaders have a variety of bullets to choose from, and Hornady lists load data for the cartridge. Brass is still available, or can be fire-formed from 7mm Remington Magnum cases.
Usage & Ballistics
While the 7x61 S&H Magnum is a good cartridge, it was overshadowed in the United States by the pre-existing 7 mm 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.
