Lee Precision PM Expander Plug .44 Special for powder through expanding die – SE2410

Lee Precision PM expand plug .44 Special – SE2410

Original Lee Precision replacement expander plug for the .44 Special caliber. It is the internal component of the powder-through expanding die, the expansion die through which the powder charge also descends in Lee progressive presses and die sets.

The plug is the element that performs the work on the case: the calibrated cylindrical portion opens the inside of the neck to the correct diameter to receive the bullet, while the short conical section at the mouth creates the case mouth flare that prevents scoring of lead or plated bullets during seating. Unlike a simple expander, the plug is drilled through its entire length so that the powder measured by the dispenser mounted above the die falls into the case in the same step as the expansion. It is a part subject to wear and is caliber-specific: it is not interchangeable between cartridges of different diameters, and a worn plug produces irregularly expanded necks, resulting in inconsistent bullet retention.
