The 7x61 Sharps & Hart cartridge is a high-velocity, bottleneck rifle cartridge developed in the early 1950s by Vern Sharps and Lenard Hart. It is designed for long-range shooting and big game hunting, offering a flat trajectory and high impact energy. The cartridge is based on the .300 H&H Magnum case, necked down to accept a 7mm bullet (.284 inch). It typically fires bullets in the range of 140 to 175 grains, achieving muzzle velocities between 3,100 to 3,400 feet per second, depending on the load.
The 7x61 Sharps & Hart is known for its accuracy and effectiveness on large game such as deer, elk, and moose. However, it never gained widespread popularity and is now considered somewhat of a specialty or custom cartridge. Despite this, it remains a respected choice among enthusiasts and hunters familiar with its performance attributes.
