This two-die set is intended for reloading bottleneck cases and consists of a Full-Length Sizer Die with an Expander-Decapping Unit, and a Seater Die with Bullet Seater Plug. The RCBS 14101 delivers precision reloading for the .284 Winchester cartridge with features built for consistent, reliable results round after round.
The Full-Length Sizer Die brings the case to SAAMI minimum cartridge dimensions. It sizes the outside of the case, de-primes and expands the neck to accept the bullet. The die has vents to prevent case damage caused by trapped air and for excessive lubricant. Headspace is held to minimum tolerances to avoid changing the case body length during full length sizing. The included Seater Die has a built-in roll crimper to secure the bullet at the same time as it’s seated. Sizing dies feature tolerances twice as stringent as typical firearms and ammunition for consistent chambering round after round, with fine body knurling for easy, non-slip adjustment.
