Estimate chamber pressure and muzzle velocity for the 475 Linebaugh 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) | 50,000 psi |
|---|---|
| Nominal case capacity | 50.0 gr H₂O |
| Groove / bullet diameter | 0.475 in (12.06 mm) |
Muzzle velocity
Peak chamber pressure (interval, ±10% burn-rate)
nominal is 67% of the 50,000 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.
