This RCBS two-die set is designed for reloading .338 Lapua Magnum bottleneck cases. The set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with Bullet Seater Plug.
The Full-Length Sizer Die resizes cases to SAAMI minimum cartridge dimensions, sizing the case exterior while de-priming and expanding the neck for bullet acceptance. Vents in the die prevent damage from trapped air and excessive lubricant. Headspace is maintained to minimum tolerances to avoid altering case body length during the full-length sizing process.
The Seater Die features a built-in roll crimper that secures the bullet while seating it simultaneously.
