Load data in caliber .260 Rem. with .264 | 160gr | Sierra SP SemiSp bullet and 90 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Alliant Reloder-26, Norma MRP and ReloadSwiss RS 70.

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 90 powders for .260 Rem. loaded with the .264 | 160gr | Sierra SP SemiSp. Alliant Reloder-26 delivers the highest muzzle velocity at 2,648 fps; across all powders the maximum-charge window runs from 1,519 fps to 2,648 fps. Accurate 3100 gives the best case fill at 100 %, and 90 of the 90 powders fall inside the usable 80–100 % fill window.

Relative to the caliber's maximum pressure (415 MPa), the top charges use 60–90 %, leaving at least 10 % headroom. The 160.0 gr projectile in 0.264" calls for a 1:11.0 twist; slower twists will usually not stabilise this weight. Accurate 3100, Accurate MAGPRO, ADI AR 2213 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, Norma MRP, ReloadSwiss RS 70 rank at the top here: for .260 Rem. with the .264 | 160gr | Sierra SP SemiSp 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.
