Load Specifications
Load data in caliber .30-30 Ackley Improved with .308 | 150gr | Alaska Bullet Works Kodiak SP SPBC bullet and 39 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Alliant AR-Comp, Hodgdon H322 and Accurate 2015.
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 73 powders for .30-30 Ackley Improved loaded with the .308 | 150gr | Alaska Bullet Works Kodiak SP SPBC. ReloadSwiss RS 52 delivers the highest muzzle velocity at 2,441 fps; across all powders the maximum-charge window runs from 1,493 fps to 2,441 fps. Accurate 2495 gives the best case fill at 100 %, and 73 of the 73 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (320 MPa), the top charges use 68–90 %, leaving at least 10 % headroom. The 150.0 gr projectile in 0.308" calls for a 1:15.5 twist; slower twists will usually not stabilise this weight. Accurate 2495, Accurate 4064, Alliant Reloder- TS 15.5 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. Alliant AR-Comp, Hodgdon H322, Accurate 2015 rank at the top here: for .30-30 Ackley Improved with the .308 | 150gr | Alaska Bullet Works Kodiak SP SPBC they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 2230, ADI AR 2206H, ADI Benchmark 8208 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.
