Load data in caliber .30-40 Krag with .308 | 180gr | NorthFork Bonded Core bullet and 59 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ReloadSwiss RS 60, Alliant Reloder-17 and Hodgdon LEVERevolution.

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.

This overview compares 59 powders for .30-40 Krag loaded with the .308 | 180gr | NorthFork Bonded Core. ReloadSwiss RS 60 delivers the highest muzzle velocity at 2,464 fps; across all powders the maximum-charge window runs from 1,496 fps to 2,464 fps. Hodgdon Hybrid 100V gives the best case fill at 100 %, and 59 of the 59 powders fall inside the usable 80–100 % fill window.

Relative to the caliber's maximum pressure (325 MPa), the top charges use 73–90 %, leaving at least 10 % headroom. The 180.0 gr projectile in 0.308" calls for a 1:12.5 twist; slower twists will usually not stabilise this weight. Hodgdon Hybrid 100V, Hodgdon TrailBoss, ReloadSwiss RS 14 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. ReloadSwiss RS 60, Alliant Reloder-17, Hodgdon LEVERevolution rank at the top here: for .30-40 Krag with the .308 | 180gr | NorthFork Bonded Core 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.
