Load Specifications
Load data in caliber 10 mm Auto (SAAMI) with .400 | 165gr | Sierra Sig V-Crown bullet and 62 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Rottweil P 806, Vihtavuori N350 and Vihtavuori 3N37.
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 ≥ 60% and propellant combustion ≥ 80%. 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.
* not dangerous but load has suboptimal powder burnt with possible characteristics such as extensive muzzle flash or inaccurate loads.
² fill rate low - you might want to consider using a filler to ensure proper ignition.
ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 25 powders for 10 mm Auto (SAAMI) loaded with the .400 | 165gr | Sierra Sig V-Crown. Rottweil P 806 delivers the highest muzzle velocity at 1,404 fps; across all powders the maximum-charge window runs from 823 fps to 1,404 fps. Alliant Herco gives the best case fill at 100 %, and 25 of the 25 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (259 MPa), the top charges use 31–90 %, leaving at least 10 % headroom. Alliant Herco, Baschieri & Pellagri 102 Pistol, Hodgdon TrailBoss 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. Rottweil P 806, Vihtavuori N350, Vihtavuori 3N37 rank at the top here: for 10 mm Auto (SAAMI) with the .400 | 165gr | Sierra Sig V-Crown they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Alliant POWER PISTOL, SNPE Vectan SP 2 burn incompletely and react more sensitively to barrel length and temperature. Alliant Herco, Alliant RED DOT, Baschieri & Pellagri 102 Pistol stay subsonic at start load. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
