Load Specifications
Load data in caliber .454 Casull Mag. with .451 | 200gr | Hornady XTP bullet and 78 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ReloadSwiss RS 24, Rottweil P 806 and Vihtavuori 3N38.
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 78 powders for .454 Casull Mag. loaded with the .451 | 200gr | Hornady XTP. Ramshot Enforcer delivers the highest muzzle velocity at 2,005 fps; across all powders the maximum-charge window runs from 1,152 fps to 2,005 fps. Accurate 4100 gives the best case fill at 100 %, and 60 of the 78 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (390 MPa), the top charges use 31–90 %, leaving at least 10 % headroom. Accurate 4100, ADI AP 100, Alliant 2400 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 24, Rottweil P 806, Vihtavuori 3N38 rank at the top here: for .454 Casull Mag. with the .451 | 200gr | Hornady XTP they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 4100, Accurate No. 9, Alliant 2400 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.
