Load data in caliber .375 Raptor with .375 | 270gr | Nosler CT FailSafe bullet and 49 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are SNPE Vectan SP 10, ADI AR 2219 and Shooters World AR Plus.

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.

This overview compares 49 powders for .375 Raptor loaded with the .375 | 270gr | Nosler CT FailSafe. Hodgdon H322 delivers the highest muzzle velocity at 2,231 fps; across all powders the maximum-charge window runs from 1,263 fps to 2,231 fps. Accurate 2015 gives the best case fill at 100 %, and 49 of the 49 powders fall inside the usable 80–100 % fill window.

Relative to the caliber's maximum pressure (400 MPa), the top charges use 54–90 %, leaving at least 10 % headroom. The 270.0 gr projectile in 0.375" calls for a 1:16.5 twist; slower twists will usually not stabilise this weight. Accurate 2015, Accurate 2460, Accurate 2495 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. SNPE Vectan SP 10, ADI AR 2219, Shooters World AR Plus rank at the top here: for .375 Raptor with the .375 | 270gr | Nosler CT FailSafe they combine a high case fill with complete burn and sit in the upper velocity band. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
