The RCBS 15402 is a 2-piece neck die set in a plastic container consisting of a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with Bullet Seater Plug. Designed for bottleneck cases to be fired in bolt-action rifles, this set is specifically intended for cases fired from a particular rifle and then neck-sized for reuse in the same rifle.
The Full-Length Sizer Die brings the case to SAAMI minimum cartridge dimensions and sizes the outside of the case while de-priming and expanding the neck to accept the bullet. The die has vents to prevent case damage caused by trapped air and excessive lubricant. The Seater Die includes a built-in roll crimper to secure the bullet while seating. This combination delivers the precision and reliability RCBS is known for in reloading equipment.
