Load Specifications
Load data in caliber 7 x 50 R with .284 | 175gr | Woodleigh PP SN bullet and 54 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are SNPE Vectan SP 10, Shooters World AR Plus and Lovex D073.4.
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 80 powders for 7 x 50 R loaded with the .284 | 175gr | Woodleigh PP SN. Alliant Power Pro 1200-R delivers the highest muzzle velocity at 2,077 fps; across all powders the maximum-charge window runs from 1,181 fps to 2,077 fps. Accurate 2015 gives the best case fill at 100 %, and 80 of the 80 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (365 MPa), the top charges use 60–90 %, leaving at least 10 % headroom. The 175.0 gr projectile in 0.284" calls for a 1:11.5 twist; slower twists will usually not stabilise this weight. 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. SNPE Vectan SP 10, Shooters World AR Plus, Lovex D073.4 rank at the top here: for 7 x 50 R with the .284 | 175gr | Woodleigh PP SN they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 2200, Accurate 2230, ADI AR 2206H burn incompletely and react more sensitively to barrel length and temperature. 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.
