Estimate chamber pressure and muzzle velocity for the 30 Super Carry 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) | 52,000 psi |
|---|---|
| Nominal case capacity | 14.5 gr H₂O |
| Groove / bullet diameter | 0.312 in (7.92 mm) |
Muzzle velocity
Peak chamber pressure (interval, ±10% burn rate)
nominal is 51% MAP (52,000 psi)
The simulator isn't optimized for this cartridge yet and may read pressure low and velocity low.
Illustrative example — every figure is an estimate; always confirm your load against a current published manual before loading.
Powders and bullets handloaders commonly use for the 30 Super Carry, drawn from public discussion and listed most common first. They appear as the Popular group in the calculator's pickers. This is not a load recommendation — always check your load against a current published manual.
Use MyLoads as a 30 Super Carry 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.
