RCBS .300 Norma Magnum Full-Length Die Set

This two-die set is designed specifically for reloading bottleneck cases and includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with a Bullet Seater Plug. The Full-Length Sizer Die resizes the case to meet SAAMI minimum cartridge dimensions, while also de-priming and expanding the neck to properly accept the bullet. The die includes vents to prevent damage from trapped air or excessive lubricant. It is designed to maintain headspace within tight tolerances, ensuring that the case body length remains consistent during full-length sizing. The Seater Die features a built-in roll crimper, which secures the bullet while it is being seated, providing a secure and reliable crimp for optimal performance.
