Load Specifications
Load data in caliber .405 Win. with .416 | 400gr | A-Square MONO RN bullet and 65 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ReloadSwiss RS 60, Hodgdon LEVERevolution and Bofors RP3.
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 84 powders for .405 Win. loaded with the .416 | 400gr | A-Square MONO RN. ReloadSwiss RS 60 delivers the highest muzzle velocity at 2,057 fps; across all powders the maximum-charge window runs from 1,207 fps to 2,057 fps. Accurate 4350 gives the best case fill at 100 %, and 84 of the 84 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (317 MPa), the top charges use 68–90 %, leaving at least 10 % headroom. Accurate 4350, Alliant Reloder-16, Alliant Reloder-17 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, Hodgdon LEVERevolution, Bofors RP3 rank at the top here: for .405 Win. with the .416 | 400gr | A-Square MONO RN they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 4350, Alliant Power Pro 2000-MR, Alliant Reloder-16 burn incompletely and react more sensitively to barrel length and temperature. Hodgdon TrailBoss, ReloadSwiss RS 14 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.
