Estimate chamber pressure and muzzle velocity for the 5.6x50 Magnum with the free, in-browser MyLoads internal ballistics simulator. The figures below are illustrative estimates from a physics model — not a recommended load. Always cross-check a current published loading manual.
| Maximum average pressure (MAP) | 3,800 BAR |
|---|---|
| Nominal case capacity | 33.5 gr H₂O |
| Groove / bullet diameter | 0.224 in (5.69 mm) |
Muzzle velocity
Peak chamber pressure (interval, ±10% burn rate)
nominal is 82% MAP (55,114 psi)
The simulator isn't optimized for this cartridge yet: there isn't enough published pressure data to check it.
Illustrative example — every figure is an estimate; always confirm your load against a current published manual before loading.
Bullets handloaders commonly use for the 5.6x50 Magnum, drawn from public discussion and listed most common first. They appear as the Popular group in the calculator's bullet picker. This is not a load recommendation — always check your load against a current published manual.
Use MyLoads as a 5.6x50 Magnum 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.
