Load Specifications
Load data in caliber .350 Legend with .355 | 175gr | Dead Nuts Ammo 350 Legend JHP bullet and 11 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are Hodgdon LilGun, Accurate No. 11 FS and Lovex S040.
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.

This overview compares 11 powders for .350 Legend loaded with the .355 | 175gr | Dead Nuts Ammo 350 Legend JHP. Hodgdon LilGun delivers the highest muzzle velocity at 2,185 fps; across all powders the maximum-charge window runs from 1,250 fps to 2,185 fps. Hodgdon TrailBoss gives the best case fill at 100 %, and 11 of the 11 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (379 MPa), the top charges use 45–89 %, leaving at least 11 % headroom. Hodgdon TrailBoss, IMR 4227, Lovex S053 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 LilGun, Accurate No. 11 FS, Lovex S040 rank at the top here: for .350 Legend with the .355 | 175gr | Dead Nuts Ammo 350 Legend JHP they combine a high case fill with complete burn and sit in the upper velocity band. Hodgdon TrailBoss 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.
