Load Specifications
Load data in caliber 7 x 50 R with .284 | 120gr | Barnes TSX BT bullet and 25 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ADI AR 2207, Norma 200 and ReloadSwiss RS 36.
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 41 powders for 7 x 50 R loaded with the .284 | 120gr | Barnes TSX BT. ADI AR 2219 delivers the highest muzzle velocity at 2,523 fps; across all powders the maximum-charge window runs from 1,473 fps to 2,523 fps. Accurate 2015 gives the best case fill at 100 %, and 41 of the 41 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (365 MPa), the top charges use 53–90 %, leaving at least 10 % headroom. The 120.0 gr projectile in 0.284" calls for a 1:11.5 twist; slower twists will usually not stabilise this weight. Accurate 2015, Accurate 2460, ADI AR 2219 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 2207, Norma 200, ReloadSwiss RS 36 rank at the top here: for 7 x 50 R with the .284 | 120gr | Barnes TSX BT they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, Accurate 2460, Accurate LT-32, Hodgdon CFE BLK 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.
