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 recipe. Always cross-check a current published loading manual.

30 Luger reference

Maximum average pressure (MAP)28,000 psi
Nominal case capacity15.5 gr H₂O
Groove / bullet diameter0.308 in (7.82 mm)

Example simulation illustrative

Bullet
Hornady 0.309 90 gr XTP
Powder
Accurate No. 7
Charge
6.5 gr
Barrel
4 in

Muzzle velocity

1,113 fps

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

17,052 – 19,812 – 22,695 psi

nominal is 71% of the 28,000 psi maximum average pressure

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.
