Lee Precision PM Expander Plug .444 Marlin for powder through expanding die – SE2052

Lee Precision PM expand plug .444 Marlin – SE2052

Original Lee Precision replacement expander plug for the .444 Marlin caliber. This is the internal component of the powder-through expanding die, the expansion die through which, in Lee progressive presses and die sets, the powder charge also drops.

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 entrance creates the flare that prevents lead or plated bullets from being scratched during seating. Unlike a simple expander, the plug is drilled through its entire length so that the powder metered by the measure mounted above the die falls into the case in the same step that the expansion takes place. It is a wear-prone part and caliber-specific: it is not interchangeable between cartridges of different diameters, and a worn plug produces irregularly expanded necks, resulting in inconsistent bullet retention.
