357 Remington Maximum Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 357 Remington Maximum with the free, in-browser MyLoads internal-ballistics simulator. The figures below are illustrative estimates from a physics model — not a recommended recipe. Always cross-check a current published loading manual.

Illustrative example — every figure here is an estimate and can be wrong. Always consult a current published loading manual, and never trust these numbers on their own.
