Powder criteria to be listed in load table


Powders listed for a specific caliber and bullet combination need to deliver loads which meet the following criteria: 
  • Achieve Fill Rate > 80% and < 100% while not exceeding allowed pressure  (loads below 80% or above 100% are typically considered unsafe)
  • Pressure for loads < 90% of Max. Standardized Pressure (more details and instructions)
  • Propellant Combustion for rifle loads > 94% (lower values typically lead to unsteady results and stronger muzzle flash)
  • Propellant Combustion for pistol / revolver loads > 90% (lower values typically lead to unsteady results and stronger muzzle flash)
