RCBS
Cast your own .358" semi-wadcutter pistol bullets with the RCBS Semi-Wadcutter Pistol Bullet Mould, a purpose-built double-cavity mould engineered for handloaders who want consistent, reliable ammunition. Whether you're loading for competition, hunting, or range work, this mould produces 158-grain projectiles sized to chamber cleanly and perform reliably downrange. RCBS has built its reputation over six decades on precision reloading equipment, and this casting tool reflects that commitment to repeatability and durability.
The heart of the mould is its solid cast-iron blocks, precision ground square and aligned with steel pins to ensure perfect mating every time you close the cavity. That geometry matters: it's the difference between batches of bullets that weigh the same and shoot to the same impact point, versus scattered results that make load development a guessing game. The double-cavity design keeps your casting pace efficient without sacrificing quality—you're producing pairs of identical projectiles with every pour.
The steel sprue plate is held firmly in place with tempered steel screws and spring washers, so it won't shift or loosen after repeated use. That solid construction means the mould performs the same whether you're casting your first batch or your thousandth, and it'll still be casting accurately for the next shooter who inherits it. If you're serious about handloading and want bullets cast to your exact specifications, this RCBS mould is the foundation of that process.
| Bullet Diameter | .358" |
| Weight | 158 grains |
| Cavity Count | Double (2) |
| Bullet Style | Semi-Wadcutter |
| Block Material | Solid cast iron |
| Sprue Plate Material | Solid steel, 3/16-inch |
This mould casts .358" diameter bullets at 158 grains, which are sized for pistol cartridges that use .358" projectiles, most commonly .38 Special and .357 Magnum. Always verify the exact diameter required by your firearm and the cartridge you're assembling before casting.
Yes. The RCBS design is straightforward and built to handle repeated use without loss of accuracy. If you're new to casting, this mould's solid construction and alignment pins make it forgiving and reliable as you develop your technique.
The facts provided describe the mould itself—the cast-iron blocks, sprue plate, and fasteners. Confirm with your retailer what additional equipment (handles, lead dippers, or flux) may be included or required separately to begin casting.
RCBS solid cast-iron blocks and steel components are engineered for decades of use. The precision ground surfaces and tempered fasteners resist wear, meaning your casting should remain consistent as long as you maintain it properly.
