9x18 Makarov Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 9x18 Makarov 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.

9x18 Makarov reference

Maximum average pressure (MAP)24,100 psi
Nominal case capacity11.0 gr H₂O
Groove / bullet diameter0.365 in (9.27 mm)

Example simulation illustrative

Bullet

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

18,167 – 22,133 – 26,218 psi

nominal is 92% of the 24,100 psi maximum average pressure

This sample load runs near the maximum average pressure for the 9x18 Makarov (about 92% of MAP at the nominal estimate; the upper interval can exceed it). It is shown only to illustrate the simulator — reduce the charge and work up from your manual's start load.

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.
