9.3x74R Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 9.3x74R 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.

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

35,405 – 46,048 – 58,585 psi

nominal is 93% of the 49,313 psi maximum average pressure

This sample load runs near the maximum average pressure for the 9.3x74R (about 93% 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.
