Load Specifications
Load data in caliber .510 Whisper with .510 | 570gr | Rhino Penetrator bullet and 33 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ADI AR 2219, Hodgdon H322 and SNPE Vectan SP 3.
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.

Recommended = one of the top powders for this cartridge and bullet combination.
ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 62 powders for .510 Whisper loaded with the .510 | 570gr | Rhino Penetrator. Alliant Power Pro 1200-R delivers the highest muzzle velocity at 1,890 fps; across all powders the maximum-charge window runs from 1,109 fps to 1,890 fps. Accurate 2495 gives the best case fill at 100 %, and 62 of the 62 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (345 MPa), the top charges use 64–90 %, leaving at least 10 % headroom. Accurate 2495, Accurate 4064, ADI AR 2206H 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. ADI AR 2219, Hodgdon H322, SNPE Vectan SP 3 rank at the top here: for .510 Whisper with the .510 | 570gr | Rhino Penetrator they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 4064, ADI AR 2206H, ADI Benchmark 8208 burn incompletely and react more sensitively to barrel length and temperature. 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.
