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 here is an estimate and can be wrong. Always consult a current published loading manual, and never trust these numbers on their own.
