Load Specifications
Load data in caliber .221 Rem. Fireball with .224 | 75gr | Speer TMJ bullet and 53 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Alliant Reloder-10x, Norma 200 and ADI AR 2207.
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 53 powders for .221 Rem. Fireball loaded with the .224 | 75gr | Speer TMJ. Alliant AR-Comp delivers the highest muzzle velocity at 2,470 fps; across all powders the maximum-charge window runs from 1,506 fps to 2,470 fps. Accurate 2015 gives the best case fill at 100 %, and 53 of the 53 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (320 MPa), the top charges use 64–90 %, leaving at least 10 % headroom. The 75.0 gr projectile in 0.224" calls for a 1:14.0 twist; slower twists will usually not stabilise this weight. Accurate 2015, Accurate 2015, Accurate 2495 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 Reloder-10x, Norma 200, ADI AR 2207 rank at the top here: for .221 Rem. Fireball with the .224 | 75gr | Speer TMJ they combine a high case fill with complete burn and sit in the upper velocity band. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
