This reference tool provides precise powder dispensing information for reloading ammunition. It correlates specific powder types with cavity sizes on the Lee Auto-Disk powder measure, offering documented drop weights. For instance, the chart might indicate that cavity ‘X’ dispenses 5.0 grains of powder ‘Y’.
The value of this documentation lies in streamlining the reloading process and improving consistency. It eliminates the need for extensive trial-and-error when determining powder charges, saving time and resources. Historically, reloaders relied on manual measurements and handwritten notes; these charts offer a pre-existing, tested starting point for charge weights.
