Lee Precision shell plate #4S for Load Master press (222 Remington, 223 Remington, 380 Auto)

Lee Precision #4S shell plate for Load Master press

The #4S shell plate is the shell carrier for the Lee Load-Master progressive press. It holds the cartridge cases by their rims and guides them through the press's five stations, from depriming and resizing to crimping, rotating 72° with each full lever cycle. It is chosen based on the rim diameter, i.e., the group of calibers you intend to reload.

Each Load-Master shell plate covers a family of cartridges that share the same rim: as long as you stay within the group, there is no need to replace it, while switching to a different rim diameter requires the corresponding plate. If the new caliber uses different size primers, the appropriate priming group (small or large) must also be provided. The plate works together with the press's indexer, flipper, and ejector; Lee Precision moved the Load-Master platform to legacy status in April 2022, and shell plates remain available as spare parts.
