RCBS Semi-Wadcutter Pistol Bullet Mould - Double Cavity .358" 158 gr

The RCBS Semi-Wadcutter Pistol Bullet Mould in .358" 158 grain with double cavity design is a precision casting tool built for reloaders who demand consistent, accurate ammunition components. Manufactured by RCBS—a company with over 60 years of experience engineering reloading equipment—this mould is machined from solid cast iron blocks engineered to exacting specifications, ensuring repeatable bullet weights and dimensions critical to reliable handload performance.

The double-cavity design accelerates production rates while maintaining the quality standards expected in precision reloading. Each cavity produces bullets with consistent geometry essential for uniform velocity, pressure curves, and shot-to-shot accuracy. The 3/16-inch sprue plate is machined from solid steel and secured with spring washers, preventing sprue separation during casting cycles and minimizing wasted lead. The .358" diameter and 158-grain weight are optimized for mid-range pistol calibers, delivering ballistic performance suitable for both target work and duty applications requiring controlled expansion and penetration characteristics.

This mould serves handloaders who reload .357 Magnum, .38 Special, or comparable pistol cartridges and require bullet consistency that factory ammunition cannot guarantee. Whether conducting precision range training, developing duty loads, or refining competition loads, the semi-wadcutter profile provides a known, predictable ballistic platform. Cast bullets from this mould offer cost-per-round advantages over jacketed alternatives while delivering the dimensional repeatability necessary for document accurate velocity and pressure data in load development work.
