NicVerAZ,
You really need to read the manual page 15.
About Powder Bars:
Dillon Precision manufactures four types of powder bars.
1. Extra Small – use for dropping less than 3 grains of powder
2. Small – use for dropping 3 to 20 grains of powder 3. Large – use for dropping 20 to approximately 45 to 50 grains of powder
4. Magnum – use for dropping 50 or more grains of powder
The extra small powder bar is used when loading .32 Auto, .32 S&W and .32 SWL. Both the extra small powder bar and the magnum powder bar are non-standard items and are ordered separately. The large and small powder bar are standard equipment and are included with every reloader.
Good luck,
.Marc
