Estimate chamber pressure and muzzle velocity for the 7.62x25 Tokarev 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.
| Maximum average pressure (MAP) | 2,500 BAR |
|---|---|
| Nominal case capacity | 16.8 gr H₂O |
| Groove / bullet diameter | 0.312 in (7.92 mm) |
Muzzle velocity
Peak chamber pressure (interval, ±10% burn-rate)
nominal is 53% of the 36,259 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.
