Load Specifications
Load data in caliber .460 S&W Mag. with .451 | 255gr | Rim Rock SWC bullet and 80 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Hodgdon LilGun, Accurate 4100 and Alliant BLUE DOT.
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.

ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 80 powders for .460 S&W Mag. loaded with the .451 | 255gr | Rim Rock SWC. Winchester 296 delivers the highest muzzle velocity at 2,041 fps; across all powders the maximum-charge window runs from 1,181 fps to 2,041 fps. Hodgdon TrailBoss gives the best case fill at 100 %, and 44 of the 80 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (427 MPa), the top charges use 38–90 %, leaving at least 10 % headroom. Hodgdon TrailBoss, ReloadSwiss RS 14, ReloadSwiss RS 30 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. Hodgdon LilGun, Accurate 4100, Alliant BLUE DOT rank at the top here: for .460 S&W Mag. with the .451 | 255gr | Rim Rock SWC they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate No. 11 FS, ReloadSwiss RS 30, Somchem S265 burn incompletely and react more sensitively to barrel length and temperature. Hodgdon TrailBoss, ReloadSwiss RS 14, Vihtavuori N32C Tin Star 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.
