Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for 7x61mm Sharpe & Hart, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

History
Designed by firearms writer P.O. Sharpe and G.H. Hart in 1953 and factory-loaded by Norma for the Danish Schultz & Larsen rifle. Delivered true magnum 7mm velocities — 160-grain bullets at approximately 3,100 fps — in a belted rimless case nearly a decade before the 7mm Remington Magnum arrived in 1962. When Remington standardized their version with better domestic factory rifle support, the S&H's commercial window closed almost immediately.
