6.5 Creedmoor Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 6.5 Creedmoor 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.

nominal is 86% of the 62,000 psi maximum average pressure

This sample load runs near the maximum average pressure for the 6.5 Creedmoor (about 86% 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 is an estimate; always confirm your load against a current published manual before loading.

Use MyLoads as a 6.5 Creedmoor 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.
