300 Savage Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 300 Savage 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.

300 Savage reference

Maximum average pressure (MAP)47,000 psi
Nominal case capacity52.0 gr H₂O
Groove / bullet diameter0.308 in (7.82 mm)

Example simulation illustrative

Bullet
Hornady 0.308 150 gr GMX
Powder
Hodgdon Varget
Charge
37.9 gr
Barrel
22 in

Muzzle velocity

2,337 fps

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

29,782 – 36,226 – 43,364 psi

nominal is 77% of the 47,000 psi maximum average pressure

Illustrative example — every figure is an estimate; always confirm your load against a current published manual before loading.

Use MyLoads as a 300 Savage 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.
