Load Specifications
Load data in caliber .454 Casull Mag. with .452 | 300gr | Hornady XTP MAG bullet and 80 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Ramshot Enforcer, Alliant BLUE DOT 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.

This overview compares 80 powders for .454 Casull Mag. loaded with the .452 | 300gr | Hornady XTP MAG. Ramshot Enforcer delivers the highest muzzle velocity at 1,562 fps; across all powders the maximum-charge window runs from 883 fps to 1,562 fps. Accurate 4100 gives the best case fill at 100 %, and 56 of the 80 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (390 MPa), the top charges use 33–90 %, leaving at least 10 % headroom. Accurate 4100, ADI AP 100, Alliant BLUE DOT 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. Ramshot Enforcer, Alliant BLUE DOT, Vihtavuori 3N38 rank at the top here: for .454 Casull Mag. with the .452 | 300gr | Hornady XTP MAG they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 4100, Alliant Power Pro 300-MP, Hodgdon H110 burn incompletely and react more sensitively to barrel length and temperature. Accurate No. 2, Accurate No. 9, Accurate Solo 1000 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.
