Prophet River Firearms

Intended for reloading 8x57mm Mauser bottleneck cases, the RCBS two-die set consists of a full-length Sizer Die with an expander-decapping unit and a Seater Die with bullet seater plug.

The Sizer Die re-shapes cases to SAAMI minimum cartridge dimensions. It sizes the outside of the case, removes the primer and expands the neck to accept the bullet. The die has vents to prevent case damage caused by trapped air and to release excessive lubricant. Headspace is held to minimum tolerances to avoid changing the case body length during full-length sizing. The included RCBS Seater Die has a built-in roll crimper to secure the bullet as it is fit into position.

Both dies have large, easy-to-adjust hex-lock rings. Each set is constructed from case-hardened steel, precision-drilled, reamed, polished and hand-inspected twice before leaving the factory. Also included with the set are a plastic storage box and loading data table.

Engineered to the highest standards and manufactured to the tightest tolerances, RCBS dies can be counted on to produce consistent and reliable results for shooters who demand reloads equal to the quality of their firearm.
