The Lyman Expander Plug Steps
The Neck-Expanding “M” die expands and flares case mouths to ease bullet seating. It is included in all three-die sets and may be purchased separately for most cartridges. Cast bullet reloaders should use this die to prevent “shaving” of bullet metal during the seating operation.
Side View
Figure 2 shows cutaway views of Neck-Expand dies with cartridge cases in position. This die is identified by the “NECK EXPAND” stamped between the knurled top and threaded shank of the die body. Note the two-step expanding plug in the die. The first step of this plug expands the neck to slightly under bullet diameter while the second step expands the first 1/16" of the neck to slightly over bullet diameter. This allows cast bullets to enter the case without shaving lead.
Adjusting the Neck-Expanding “M” Die: Remove the expanding plug stem from the die body. Loosen the set screw and die lock ring and back off the die lock ring for sufficient room to screw the die body into the press. Lower the press handle until the shellholder is at its highest point, then screw the die into the press until the die’s bottom edge made light contact with the shellholder. The die body is now adjusted. Turn down the lock ring and tighten its set screw.
Your expanding plug must now be adjusted to the proper depth. Start the expanding plug stem into the die body. Place an empty, sized cartridge
case in the shellholder and lower the press handle until the shellholder is again at its highest point. Turn in the expander plug stem until you feel the expander plug contact the case mouth. This means the first (and narrower) stage of the plug is entering the case mouth.
Lift and lower the press handle slightly while continuing to adjust the expanding plug stem until it flares the case mouth. The case mouth should be flared enough to allow your bullet to easily enter the mouth without shaving lead or jacket material. With the Neck-Expanding Die adjusted, secure the expander plug lock nut.

 1) First step expands inside

case neck tension in the finished reload. |
 2) Second step expands case
mouth to bullet diameter or slightly over. Jacketed orcast bullets start perfectly centered and properly aligned w/ axis of caseneck. |
 NOTE:
By adjusting the neck expanding plug slightly deeper,
Step 2 also provides a slight flaring of case
mouth for reloaders using cast bullets. |
