Hornady Shotshell Press Bushing Guide

Hornady powder bushings are identified by numbers that correspond to the size oftheir inside diameter. (The inside diameter of the #456 bushing is 0.456".) Bushings for powder charges in half-grainincrements can be calculated from this chart. Simply "split the difference" between the two evengrain bushings and selectthe bushing nearest the result.

Due to agitation of powder during loadingoperation, different models of loaders require different bushings. Therefore, the chart should be used only for 366 AUTO and Hornady's APEX. Additional charts are published for other Hornady loaders.

All charges listed on this chart are an averageof several loads, weighed following the complete reloading cycle. Powders Used in establishing these loads were from ballistic samples suppliedby the manufacturer or sealed tins of recent manufacture.

Example: To find the bushing for 18-1/2 grains of Alliant Red Dot powder. Bushing #468 gives a charge of 18 grains and bushing #480 gives 19 grains. Split the difference between 468 and 480 andthe result is 474.Therefore the correctbushing for 18-1/2 grains of Red Dot is bushing #474. Charges may vary slightly due to operator'stechnique and/or powder variables.
