7.5x54 MAS Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 7.5x54 MAS 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.

nominal is 64% MAP (55,114 psi)

The simulator isn't optimized for this cartridge yet: there isn't enough published pressure data to check it.

Illustrative example — every figure is an estimate; always confirm your load against a current published manual before loading.

Popular 7.5x54 MAS powders

Powders and bullets handloaders commonly use for the 7.5x54 MAS, drawn from public discussion and listed most common first. They appear as the Popular group in the calculator's pickers. This is not a load recommendation — always check your load against a current published manual.
