RCBS 15201 Full-Length Die Set for .300 Weatherby Magnum

The RCBS 15201 Full-Length Die Set is designed for reloading bottleneck cases in .300 Weatherby Magnum. This two-die set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with a Bullet Seater Plug, providing the essential tools for sizing, depriming, neck expansion, and bullet seating. The set is suited for reloaders who want consistent case preparation and reliable cartridge assembly.
The Full-Length Sizer Die returns cases to SAAMI minimum cartridge dimensions while sizing the outside of the case, removing the spent primer, and expanding the neck to accept a new bullet. Built-in vents help reduce the risk of case damage caused by trapped air or excess lubricant during sizing. The die also maintains headspace within minimum tolerances to help prevent unwanted changes to the case body length during the full-length sizing process.
The included Seater Die features an integrated roll crimper that secures the bullet as it is seated. This design combines two important loading steps in a single operation and is suitable for applications where a firm, consistent crimp is desired. With its practical two-die configuration and RCBS construction, the 15201 die set provides a dependable solution for .300 Weatherby Magnum case preparation and reloading.
