Load Specifications
Load data in caliber 7.62 x 53 R Fin. with .308 | 85gr | Lehigh Defense Xtreme Penetrator bullet and 31 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ADI AR 2219, Norma 200 and Hodgdon H322.
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 54 powders for 7.62 x 53 R Fin. loaded with the .308 | 85gr | Lehigh Defense Xtreme Penetrator. Alliant Power Pro 1200-R delivers the highest muzzle velocity at 3,730 fps; across all powders the maximum-charge window runs from 2,303 fps to 3,730 fps. Accurate 2015 gives the best case fill at 100 %, and 54 of the 54 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (390 MPa), the top charges use 53–90 %, leaving at least 10 % headroom. Accurate 2015, Accurate 2495, Accurate 2520 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. ADI AR 2219, Norma 200, Hodgdon H322 rank at the top here: for 7.62 x 53 R Fin. with the .308 | 85gr | Lehigh Defense Xtreme Penetrator they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 2520, ADI Benchmark 8208, Alliant Power Pro 1200-R 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.
