Load Specifications
Load data in caliber .369 N.E. Purdey with .375 | 235gr | Speer Hot-Cor bullet and 29 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Somchem S365, Hodgdon Hybrid 100V and Winchester 6.5 StaBALL.
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 51 powders for .369 N.E. Purdey loaded with the .375 | 235gr | Speer Hot-Cor. ReloadSwiss RS 60 delivers the highest muzzle velocity at 2,782 fps; across all powders the maximum-charge window runs from 1,778 fps to 2,782 fps. Accurate 3100 gives the best case fill at 100 %, and 51 of the 51 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (305 MPa), the top charges use 73–90 %, leaving at least 10 % headroom. Accurate 3100, Alliant Reloder-23, 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. Somchem S365, Hodgdon Hybrid 100V, Winchester 6.5 StaBALL rank at the top here: for .369 N.E. Purdey with the .375 | 235gr | Speer Hot-Cor they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 3100, Bofors RP7, Hodgdon H414 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.
