Lyman Neck Expanding M Pro Die 22S (LY7704160)

Lyman Pro Neck-Expanding “M” die uses the same famous two-step expander plug as standard Lyman “M” dies but all other components are made from tough, anti-corrosive stainless steel. The two-step expander provides the proper neck tension as well as slightly opening the case mouth to allow the bullet to just start into the case. This keeps the bullet in place as it is cycled to the bullet seating station. It also allows the bullet to seat smoothly into the case with no shaving or scoring.
