RCBS 12801 Full Length Die Set 260 Remington

The RCBS 12801 is a two-die set curated specifically for the purpose of reloading bottleneck cases. The set is composed of a Full-Length Sizer Die which includes an Expander-Decapping Unit, and a Seater Die equipped with a Bullet Seater Plug.

The Full-Length Sizer Die shapes the case to match the Saami minimum cartridge dimensions. It modifies the exterior of the case, removes the primer, and expands the neck to fit the bullet. The die features vents designed to prevent potential case damage that can be caused by trapped air or excessive lubricant. Furthermore, the headspace is kept to the smallest possible tolerances to ensure that the case body length doesn't change during full-length sizing.

The accompanying Seater Die comes in-house with a roll crimper. This feature isn't just for decoration - it securely fixes the bullet in its place during the seating process.
