Load Specifications
Load data in caliber .22-250 Ackley Improved with .222 | 52gr | Frontier PH Phlanx bullet and 72 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ReloadSwiss RS 60, Ramshot Big Game and Hodgdon LEVERevolution.
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.

Recommended = one of the top powders for this cartridge and bullet combination.
ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 93 powders for .22-250 Ackley Improved loaded with the .222 | 52gr | Frontier PH Phlanx. ReloadSwiss RS 60 delivers the highest muzzle velocity at 3,691 fps; across all powders the maximum-charge window runs from 2,313 fps to 3,691 fps. Accurate 4350 gives the best case fill at 100 %, and 93 of the 93 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (400 MPa), the top charges use 58–90 %, leaving at least 10 % headroom. The 52.0 gr projectile in 0.222" calls for a 1:7.5 twist; slower twists will usually not stabilise this weight. Accurate 4350, Alliant Reloder-16, Alliant Reloder-17 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. ReloadSwiss RS 60, Ramshot Big Game, Hodgdon LEVERevolution rank at the top here: for .22-250 Ackley Improved with the .222 | 52gr | Frontier PH Phlanx they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 4350, Alliant Reloder-16, Hodgdon Hybrid 100V 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.
