Load Specifications
Load data in caliber 7.62 x 39 (.308) Russian with .311 | 190gr | Winchester Silvertip bullet and 30 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Hodgdon H322, Alliant Reloder-10x and Norma 200.
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.

Recommended = one of the top powders for this cartridge and bullet combination.
ᴾ possible press load - work up slowly to this load while watching for signs of excessive pressure.
This overview compares 30 powders for 7.62 x 39 (.308) Russian loaded with the .311 | 190gr | Winchester Silvertip. SNPE Vectan SP 10 delivers the highest muzzle velocity at 1,929 fps; across all powders the maximum-charge window runs from 1,148 fps to 1,929 fps. Accurate 2015 gives the best case fill at 100 %, and 30 of the 30 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (355 MPa), the top charges use 61–90 %, leaving at least 10 % headroom. The 190.0 gr projectile in 0.311" calls for a 1:6.0 twist; slower twists will usually not stabilise this weight. Accurate 2015, Accurate 2495, Alliant AR-Comp 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 H322, Alliant Reloder-10x, Norma 200 rank at the top here: for 7.62 x 39 (.308) Russian with the .311 | 190gr | Winchester Silvertip 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.
