Product Features & Specifications

RCBS 12501 Full-Length 2-Die Set Group A .257 Roberts

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 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.
