The Lee Precision powder through expander die allows you to bell the case mouth and charge with powder in one step. A belling cone opens the case mouth for bullet seating alignment while providing a nice, open port sealed to the case for powder charging in one convenient step!
Only Lee dies permit charging the case while expanding the case mouth. Every Lee 3-die Set includes the Powder Through Expanding Die at no extra cost. The Powder Funnel adapter can be replaced with a Lee Auto-Disk Powder Measure for fully automatic powder charging while the case mouth is being expanded. Shell holder sold separately.
