Load Specifications
Load data in caliber .45 Win. Mag. with .451 | 230gr | Speer HPSB GD bullet and 62 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Vihtavuori N105, ADI AP 100 and SNPE Vectan BA7 1/2.
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 12 powders for .45 Win. Mag. loaded with the .451 | 230gr | Speer HPSB GD. Vihtavuori N105 delivers the highest muzzle velocity at 1,483 fps; across all powders the maximum-charge window runs from 925 fps to 1,483 fps. Hodgdon TrailBoss gives the best case fill at 100 %, and 12 of the 12 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (275 MPa), the top charges use 39–90 %, leaving at least 10 % headroom. Hodgdon TrailBoss, ReloadSwiss RS 14, Vihtavuori N105 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. Vihtavuori N105, ADI AP 100, SNPE Vectan BA7 1/2 rank at the top here: for .45 Win. Mag. with the .451 | 230gr | Speer HPSB GD they combine a high case fill with complete burn and sit in the upper velocity band. Baschieri & Pellagri 102 Pistol, 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.
