Load Specifications
Load data in caliber .219 Donaldson Wasp with .224 | 63gr | Sierra VarmintKing bullet and 17 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Accurate 4064, Vihtavuori N135 and Accurate 2495.
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 17 powders for .219 Donaldson Wasp loaded with the .224 | 63gr | Sierra VarmintKing. IMR 3031 delivers the highest muzzle velocity at 2,864 fps; across all powders the maximum-charge window runs from 1,932 fps to 2,864 fps. Hodgdon TrailBoss gives the best case fill at 100 %, and 17 of the 17 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (283 MPa), the top charges use 81–90 %, leaving at least 10 % headroom. The 63.0 gr projectile in 0.224" calls for a 1:12.0 twist; slower twists will usually not stabilise this weight. 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. Accurate 4064, Vihtavuori N135, Accurate 2495 rank at the top here: for .219 Donaldson Wasp with the .224 | 63gr | Sierra VarmintKing 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.
