NOTE:
The amount of powder thrown by bushings was calculated using single-stage reloaders. Single-stage machines will
usually throw heavier charges than progressive reloading machines. Please verify powder loads by using an accurate
scale.
Compatible Components
Primers, wads, powder charge and weight of the shot charge must be in accordance with the manufacturer's specifications.
Handloader guides are available from the component manufacturer or possibly from your source of reloading components.
We recommend that you use the data listed in the handloader guides. Because we have no control over the type, quality,
or quantity of components used, we assume no responsibility relative to your reloading or finished shells.
Handloader guides are available from:
