The RCBS .243 Winchester Full Length Die Set 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, sizes the outside of the case, de-primes, and expands the neck to accept the bullet, with vents to prevent case damage caused by trapped air and 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. The dies are standard 7/8 x 14 thread size, compatible with most reloading presses. The set includes a plastic storage box and loading data table for convenient storage and reference. RCBS Precision engineered Dies are designed for shooters who demand reloads equal to the quality of their guns, with each die properly hardened and hand polished.
