7mm-08 Remington Load Data & Ballistics Calculator

Estimate chamber pressure and muzzle velocity for the 7mm-08 Remington 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.

7mm-08 Remington reference

Maximum average pressure (MAP)61,000 psi
Nominal case capacity52.2 gr H₂O
Groove / bullet diameter0.284 in (7.21 mm)

Example simulation illustrative

Bullet
Hornady 0.284 139 gr GMX
Powder
IMR 4064
Charge
34.1 gr
Barrel
24 in

Muzzle velocity

2,338 fps

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

28,780 – 34,402 – 40,591 psi

nominal is 56% of the 61,000 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 7mm-08 Remington 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.
