Universal Charging Die Bushings

Be sure you have the correct bushing installed in the universal charge die.  The case mouth adapter is the brass bushing with straight sides.  The other two have a step or a change in outside diameter.  The case mouth adapter is installed with the deeper chamfer facing up. 

For most pistol cartridges, use the longer of the two stepped bushings, with the smaller outside diameter facing down. 

When using the die with rifle cartridges, you need to pause for a second or two at the top of the stroke (lever down, carrier up) to allow for the powder to flow from the hopper into the case.
