Load Specifications
Load data in caliber .360 Buckhammer with .358 | 200gr | NorthFork Bonded Core bullet and 17 powders. The key underlying parameters are shown in the table above. The recommended powders for this cartridge and bullet combination are ReloadSwiss RS 36, Lovex S053 and IMR 4227.
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 21 powders for .360 Buckhammer loaded with the .358 | 200gr | NorthFork Bonded Core. ReloadSwiss RS 36 delivers the highest muzzle velocity at 2,139 fps; across all powders the maximum-charge window runs from 1,276 fps to 2,139 fps. ADI AR 2207 gives the best case fill at 100 %, and 21 of the 21 powders fall inside the usable 80–100 % fill window.
Relative to the caliber's maximum pressure (345 MPa), the top charges use 54–90 %, leaving at least 10 % headroom. ADI AR 2207, Alliant Reloder-7, Hodgdon TrailBoss 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. ReloadSwiss RS 36, Lovex S053, IMR 4227 rank at the top here: for .360 Buckhammer with the .358 | 200gr | NorthFork Bonded Core they combine a high case fill with complete burn and sit in the upper velocity band. As outliers, IMR 4198, Norma 200 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.
