Load Specifications
Load data in caliber .308 Marlin Express with .311 | 182gr | Prvi Partizan FMJ BT bullet and 56 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are IMR 3031, Winchester 748 and Hodgdon BL-C2.
Important Notice: DO NOT go below Minimum Charge or above Maximum Charge. Since we have no control over the equipment and components used, any responsibility and liability for the results achieved is rejected.
Only powders/loads that match the current filter criteria are displayed: max pressure of a load ≤ 90% of max. standardized pressure, fill rate ≥ 80% and propellant combustion ≥ 95%. Use the sliders above the tables to adjust these thresholds.
Charge: Powder weight in grains. Start with the minimum load and work up carefully.
FR (Fill Rate): Case fill as a percentage. Values above 100% mean compressed loads.
MaxP / %: Maximum chamber pressure in bar and as a percentage of the standardized maximum for this caliber.
V(0): Muzzle velocity in feet per second (fps) at the standardized barrel length.
z (Powder Burn): Estimated propellant combustion percentage at bullet exit.

Recommended = one of the top powders for this cartridge and bullet combination.
ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 56 powders for .308 Marlin Express loaded with the .311 | 182gr | Prvi Partizan FMJ BT. Hodgdon BL-C2 delivers the highest muzzle velocity at 2,320 fps; across all powders the maximum-charge window runs from 1,391 fps to 2,320 fps. Accurate 4064 gives the best case fill at 100 %, and 56 of the 56 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (330 MPa), the top charges use 69–90 %, leaving at least 10 % headroom. The 182.0 gr projectile in 0.311" calls for a 1:12.5 twist; slower twists will usually not stabilise this weight. Accurate 4064, Alliant Reloder- TS 15.5, Bofors RP3 reach 100 % fill or more at maximum charge, so these are compressed loads: they need a long drop tube to seat cleanly and react sensitively to the case capacity of your own brass lot. IMR 3031, Winchester 748, Hodgdon BL-C2 rank at the top here: for .308 Marlin Express with the .311 | 182gr | Prvi Partizan FMJ BT they combine a high case fill with complete burn and sit in the upper velocity band. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
