The 7x61mm Sharpe & Hart Magnum belted cartridge (7mm S&H Super) was developed by Philip Sharpe and Richard Hart in the 1950s. In 1953 Schultz & Larson of Denmark chambered the cartridge in their hbolt action rifles, based on the .300 H&H Magnum case. Norma used to make commercial ammunition, but now it is a handloader's perspective. Today's handloaders have a variety of bullets to choose from, and Hornady lists load data for the cartridge.

[edit] 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 7mm Remington Magnum cartridge was introduced it spelled the demise of the 7x61 S&H.
