Lee Precision PM Expander Plug .45 Colt for powder through expanding die – SE2412

Lee Precision PM expand plug .45 Colt – SE2412

Original Lee Precision replacement expander plug for the .45 Colt caliber. This is the internal component of the powder-through expanding die, the expansion die through which the powder charge also drops in Lee progressive presses and die sets. Lee catalogs this code as PM EXPAND PLG 45COLT and lists it as a spare part for the Load-Master .45 Colt press (code 90946).

The plug is the element that determines the work performed on the case: the calibrated cylindrical portion opens the inside of the neck to the correct diameter to accept the bullet, while the short conical section at the mouth creates the flare that prevents lead or plated bullets from being shaved during seating. Unlike a simple expander, the plug is hollowed out throughout its length, allowing the powder measured by the dispenser mounted above the die to fall into the case during the same stroke as the expansion. This is a wear-prone, caliber-specific part: it is not interchangeable between cartridges of different diameters, and a worn plug will produce irregularly expanded necks, resulting in inconsistent bullet retention.
