Load Specifications
Load data in caliber .405 Win. with .416 | 220gr | Reichenberg Spezial Jagd bullet and 15 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Norma 200, Alliant Reloder-10x and Alliant Reloder-7.
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.

ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 35 powders for .405 Win. loaded with the .416 | 220gr | Reichenberg Spezial Jagd. Hodgdon H335 delivers the highest muzzle velocity at 2,674 fps; across all powders the maximum-charge window runs from 1,647 fps to 2,674 fps. Accurate 2015 gives the best case fill at 100 %, and 35 of the 35 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (317 MPa), the top charges use 63–90 %, leaving at least 10 % headroom. Accurate 2015, Accurate 2460, Alliant AR-Comp 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. Norma 200, Alliant Reloder-10x, Alliant Reloder-7 rank at the top here: for .405 Win. with the .416 | 220gr | Reichenberg Spezial Jagd they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 2460, Accurate LT-30, Accurate LT-32 burn incompletely and react more sensitively to barrel length and temperature. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
