30 Luger Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 30 Luger 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.

30 Luger reference

Muzzle velocity

1,068 fps

Peak chamber pressure (interval, ±10% burn rate)

20,427 – 23,156 – 25,821 psi

nominal is 83% MAP (28,000 psi)

The simulator isn't optimized for this cartridge yet and may read pressure high or low.

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

Popular 30 Luger powders

Powders handloaders commonly use for the 30 Luger, drawn from public discussion and listed most common first. They appear as the Popular group in the calculator's powder picker. This is not a load recommendation — always check your load against a current published manual.

Use MyLoads as a 30 Luger velocity and pressure calculator: it estimates muzzle velocity, muzzle energy and the full chamber-pressure curve for your own powder, charge and barrel length, compared against the reference facts above.
