Lee Precision PM Expander Plug .38 Special and .357 Magnum SE2408

PM Expander Plug .38 Special / .357 Magnum SE2408

The expander plug is the internal tip of the Lee Precision Powder Through Expanding Die, the die that flares the case mouth and simultaneously allows powder to flow from the powder measure into the case. This original spare part allows you to return a die with a worn or damaged tip to service without replacing the entire assembly.

The plug works in tandem with the expander body and sealing O-rings: the diameter of the step determines the extent of the flare and, consequently, how easily the bullet seats on the case neck. The dimension is caliber-specific, so the plugs are not interchangeable between different calibers; in recent versions, Lee has adopted the stepped profile known as the "M style," which creates a short cylindrical section before the flare.
