Load Specifications
Load data in caliber 6.5 x 57 R with .264 | 128gr | Peregrine VLR-5 bullet and 34 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Alliant Reloder-26, Alliant Reloder-16 and Winchester StaBALL HD.
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 65 powders for 6.5 x 57 R loaded with the .264 | 128gr | Peregrine VLR-5. Alliant Reloder-26 delivers the highest muzzle velocity at 2,805 fps; across all powders the maximum-charge window runs from 1,732 fps to 2,805 fps. Alliant Reloder-25 gives the best case fill at 100 %, and 65 of the 65 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (330 MPa), the top charges use 75–90 %, leaving at least 10 % headroom. The 128.0 gr projectile in 0.264" calls for a 1:8.0 twist; slower twists will usually not stabilise this weight. Alliant Reloder-25, Bofors RP15, Hodgdon Retumbo 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-26, Alliant Reloder-16, Winchester StaBALL HD rank at the top here: for 6.5 x 57 R with the .264 | 128gr | Peregrine VLR-5 they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, ADI AR 2209, ADI AR 2213, Alliant Reloder-19 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.
