Load Specifications
Load data in caliber .50 BMG with .510 | 802gr | CutEdge MTAC bullet and 29 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ADI AR 2218, Alliant Reloder-50 and Alliant Reloder-33.
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.

ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 31 powders for .50 BMG loaded with the .510 | 802gr | CutEdge MTAC. ADI AR 2218 delivers the highest muzzle velocity at 2,507 fps; across all powders the maximum-charge window runs from 1,503 fps to 2,507 fps. Hodgdon TrailBoss gives the best case fill at 100 %, and 31 of the 31 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (370 MPa), the top charges use 71–90 %, leaving at least 10 % headroom. The 802.0 gr projectile in 0.51" calls for a 1:16.5 twist; slower twists will usually not stabilise this weight. Hodgdon TrailBoss, ReloadSwiss RS 14, Vihtavuori 20N29 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 2218, Alliant Reloder-50, Alliant Reloder-33 rank at the top here: for .50 BMG with the .510 | 802gr | CutEdge MTAC they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Hodgdon 50BMG burn incompletely and react more sensitively to barrel length and temperature. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
