A graduated table provides a reference for correlating volumetric cavities within a powder dispensing device with the corresponding weight of a specific propellant. These charts typically list various cavity sizes, expressed in cubic centimeters or similar units, alongside the estimated weight of powder that cavity will hold for a given propellant type. For example, a user might consult the table to determine that a 0.300cc cavity will dispense approximately 4.5 grains of Hodgdon H110 powder.
These tables are essential for reloaders seeking to achieve consistent and accurate ammunition. They eliminate the need for extensive trial and error, offering a starting point for charge weight selection. Historical powder measures often relied on hand-dipping or less precise methods; standardized reference materials greatly improved the safety and repeatability of the reloading process, contributing to more uniform ballistic performance and reduced risks associated with over or under-powered cartridges.
