RCBS 16601 Full-Length Die Set for .338 Lapua Magnum, 2-Piece

The RCBS 16601 Full-Length Die Set is designed for reloading bottleneck cases in .338 Lapua Magnum. This two-piece set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with a Bullet Seater Plug. It provides the core die functions needed to resize, de-prime, expand, and seat bullets during the reloading process.
The Full-Length Sizer Die brings the case to SAAMI minimum cartridge dimensions while sizing the outside of the case and expanding the neck to accept a bullet. Its integrated Expander-Decapping Unit removes the spent primer and prepares the case neck for bullet seating. Vent openings help reduce the risk of case damage caused by trapped air or excessive lubricant, while carefully controlled headspace tolerances help prevent unwanted changes to the case body length during full-length sizing.
The included Seater Die features a built-in roll crimper that secures the bullet as it is seated. This design combines bullet seating and crimping in one operation, supporting consistent ammunition assembly when properly adjusted for the intended load and components. Built for reloaders who need reliable sizing and seating functions for the .338 Lapua Magnum cartridge, the RCBS 16601 die set offers a practical addition to a precision reloading setup.
