Load data in caliber 5.56 x 45 NATO with .224 | 70gr | Barnes TSX BT bullet and 159 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ADI AR 2219, Hodgdon H335 and SNPE Vectan SP 10.
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 159 powders for 5.56 x 45 NATO loaded with the .224 | 70gr | Barnes TSX BT. Alliant Power Pro 1200-R delivers the highest muzzle velocity at 2,884 fps; across all powders the maximum-charge window runs from 1,657 fps to 2,884 fps. Accurate 2015 gives the best case fill at 100 %, and 159 of the 159 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (430 MPa), the top charges use 51–90 %, leaving at least 10 % headroom. The 70.0 gr projectile in 0.224" calls for a 1:8.0 twist; slower twists will usually not stabilise this weight. Accurate 2015, Accurate 2015, Accurate 2015 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. ADI AR 2219, Hodgdon H335, SNPE Vectan SP 10 rank at the top here: for 5.56 x 45 NATO with the .224 | 70gr | Barnes TSX BT 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.
