HOW TO SELECT BUSHINGS FOR HALF GRAIN CHARGES:
Powder bushings are identified by numbers that correspond to
the size of their inside diameter. (For instance, the inside
diameter of the #456 bushing is .456 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 18 1/2 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 18 1/2 grains of Red Dot is bushing #474.
All charges listed on this chart are an average of several loads,
weighed following the complete reloading cycle. Powders used
in establishing these loads were from ballistic samples supplied
by the manufacturer or sealed tins of recent manufacture.
Charges may vary slightly due to operator's technique and/or
powder variables.
