Load Specifications
Load data in caliber .375 Win. with .375 | 175gr | CutEdge Maximus bullet and 12 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Hodgdon LilGun, Accurate No. 11 FS and ADI AR 2205.
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 20 powders for .375 Win. loaded with the .375 | 175gr | CutEdge Maximus. Hodgdon LilGun delivers the highest muzzle velocity at 2,490 fps; across all powders the maximum-charge window runs from 1,417 fps to 2,490 fps. Accurate 1680 gives the best case fill at 100 %, and 20 of the 20 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (380 MPa), the top charges use 44–89 %, leaving at least 11 % headroom. Accurate 1680, ADI AR 2207, Hodgdon TrailBoss 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. Hodgdon LilGun, Accurate No. 11 FS, ADI AR 2205 rank at the top here: for .375 Win. with the .375 | 175gr | CutEdge Maximus they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 1680, ADI AR 2207 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.
