5.6x50R Magnum Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 5.6x50R Magnum with the free, in-browser MyLoads internal ballistics simulator. The figures below are illustrative estimates from a physics model — not a recommended load. Always cross-check a current published loading manual.
