Product Description
Hornady powder bushings are identified by numbers that correspond to the size of their inside diameter. (For instance, the inside diameter of the #558 bushing is .558 inches.) Bushings for powder charges in half-grain increments can be calculated from this chart. Simply “split the difference” between the two even- grain bushings, and select the bushing nearest the result.
Example: To find the bushing for 18½ grains of Hercules Red Dot powder, note that bushing #468 gives a charge of 18 grains and that bushing #480 gives 19 grains. Split the difference between 468 and 480, and the result is 474. Thus, the correct bushing for 18½ grains of Red Dot is bushing #474.
