Load data in caliber 7.5 x 55 Swiss with .308 | 130gr | Barnes X BT bullet and 81 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ReloadSwiss RS 60, ReloadSwiss RS 52 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 81 powders for 7.5 x 55 Swiss loaded with the .308 | 130gr | Barnes X BT. Alliant Power Pro 2000-MR delivers the highest muzzle velocity at 3,281 fps; across all powders the maximum-charge window runs from 1,955 fps to 3,281 fps. Accurate 4350 gives the best case fill at 100 %, and 81 of the 81 powders fall inside the usable 80–100 % fill window.

Relative to the caliber's maximum pressure (380 MPa), the top charges use 63–90 %, leaving at least 10 % headroom. The 130.0 gr projectile in 0.308" calls for a 1:14.0 twist; slower twists will usually not stabilise this weight. Accurate 4350, Alliant Reloder-16, Hodgdon Hybrid 100V 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. ReloadSwiss RS 60, ReloadSwiss RS 52, Alliant Power Pro 2000-MR rank at the top here: for 7.5 x 55 Swiss with the .308 | 130gr | Barnes X 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.
