Load data in caliber .277 Fury with .277 | 140gr | Winchester FailSafe bullet and 120 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Hodgdon CFE223, Alliant Power Pro 1200-R and Alliant Power Pro 2000-MR.

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.

This overview compares 120 powders for .277 Fury loaded with the .277 | 140gr | Winchester FailSafe. Alliant Power Pro 2000-MR delivers the highest muzzle velocity at 3,071 fps; across all powders the maximum-charge window runs from 1,637 fps to 3,071 fps. Accurate 2495 gives the best case fill at 100 %, and 120 of the 120 powders fall inside the usable 80–100 % fill window.

Relative to the caliber's maximum pressure (552 MPa), the top charges use 41–90 %, leaving at least 10 % headroom. The 140.0 gr projectile in 0.277" calls for a 1:11.0 twist; slower twists will usually not stabilise this weight. Accurate 2495, Accurate 2700, Accurate 4064 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. Hodgdon CFE223, Alliant Power Pro 1200-R, Alliant Power Pro 2000-MR rank at the top here: for .277 Fury with the .277 | 140gr | Winchester FailSafe 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.
