Load Specifications
Load data in caliber .30 Super Fl. H&H with .308 | 180gr | Nosler Partition bullet and 24 powders. The key underlying parameters are shown in the table above.
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 24 powders for .30 Super Fl. H&H loaded with the .308 | 180gr | Nosler Partition. ReloadSwiss RS 76 delivers the highest muzzle velocity at 2,858 fps; across all powders the maximum-charge window runs from 1,821 fps to 2,858 fps. ADI AR 2225 gives the best case fill at 100 %, and 24 of the 24 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (320 MPa), the top charges use 79–90 %, leaving at least 10 % headroom. The 180.0 gr projectile in 0.308" calls for a 1:14.5 twist; slower twists will usually not stabilise this weight. ADI AR 2225, Hodgdon TrailBoss, ReloadSwiss RS 14 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. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
