Load Specifications
Load data in caliber 7.62 x 39 (.308) Russian with .308 | 165gr | Remington SP Extended-Range BT bullet and 17 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Norma 200, ADI AR 2207 and Vihtavuori N120.
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 7.62 x 39 (.308) Russian loaded with the .308 | 165gr | Remington SP Extended-Range BT. Alliant Reloder-10x delivers the highest muzzle velocity at 2,037 fps; across all powders the maximum-charge window runs from 1,224 fps to 2,037 fps. Alliant AR-Comp 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 (355 MPa), the top charges use 58–89 %, leaving at least 11 % headroom. The 165.0 gr projectile in 0.308" calls for a 1:6.0 twist; slower twists will usually not stabilise this weight. Alliant AR-Comp, Alliant Reloder-10x, Hodgdon TrailBoss 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. Norma 200, ADI AR 2207, Vihtavuori N120 rank at the top here: for 7.62 x 39 (.308) Russian with the .308 | 165gr | Remington SP Extended-Range BT they combine a high case fill with complete burn and sit in the upper velocity band. Hodgdon TrailBoss, ReloadSwiss RS 14 stay subsonic at start load. Always begin at the start load and work up in small increments while checking case and primer for pressure signs.
