Estimate chamber pressure and muzzle velocity for the 260 Remington 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.
260 Remington reference
Maximum average pressure (MAP)
60,000 psi
Nominal case capacity
53.5 gr H₂O
Groove / bullet diameter
0.264 in (6.71 mm)
Example simulation illustrative
Bullet
Sierra 6.5mm 264 Caliber (.264) 107 gr HPBT MatchKing
Powder
Alliant Reloder 16
Charge
38.8 gr
Barrel
24 in
Muzzle velocity
2,725 fps
Peak chamber pressure (interval, ±10% burn rate)
30,582 – 39,184 – 48,875 psi
nominal is 65% MAP (60,000 psi)
Pressure for this powder is extrapolated from a velocity-only fit — the pressure figures carry extra uncertainty in both directions.
Illustrative example — every figure is an estimate; always confirm your load against a current published manual before loading.
