The RCBS Bullet Mould .308-165-SIL (Manufacturer Part Number: 82152 / R82152) is a premium 2-cavity hand-casting block engineered for casting high-accuracy .30 caliber rifle projectiles. Machined from solid, pearlitic malleable cast iron, this mold is built for exceptional thermal stability and long-term durability. It casts two 165-grain Gas Check (GC) silhouette bullets simultaneously, ensuring excellent consistency in weight and diameter. Since this is a purely mechanical, non-electrical hand tool, it is fully compatible for use in Australian workspaces without requiring electrical safety certifications, though users should ensure a well-ventilated casting environment due to the heat and molten lead involved.

Key Features

• Dual-Cavity Block: Casts two 165-grain projectiles simultaneously to balance production speed and cast quality.
• Pearlitic Cast Iron Construction: Malleable iron blocks resist warping and maintain stable operating temperatures during casting cycles.
• Precision Alignment: Features precision-ground mating faces and steel alignment pins to ensure the mold halves lock together perfectly without shifting.
• Heavy-Duty Sprue Plate: Features a 3/16-inch thick solid steel sprue plate held securely by tempered steel spring washers and screws to ensure clean sprue cuts.
• Gas-Check Base Design: Designed for a crimped-on copper gas check, enabling the cast bullets to withstand higher velocities and pressures without bore leading.

Who is the Rcbs Bullet Mould .308-165-Sil for?

• Metallic silhouette target shooters — requiring extreme accuracy at standard ranges of 100 to 200 yards (91 to 182 meters), which this rifle bullet mould achieves by casting consistent 165-grain gas-check bullets that can be driven at velocities up to 2,100 feet per second.
• Precision cast-bullet hunters — who need to cast their own 165-grain .30-caliber projectiles for cartridges like the .308 Winchester or .30-06 Springfield, benefiting from a durable cast-iron block that stabilizes bullet weights for optimal performance in medium-twist rifle barrels.

Less suitable for: high-volume reloaders who need to cast thousands of handgun rounds quickly, as this manual 2-cavity iron mould is slower than multi-cavity aluminum moulds (such as 4-cavity or 6-cavity blocks); it is also less suitable for shooters requiring bullet velocities exceeding 2,100 feet per second, where shooters must transition to copper-jacketed projectiles to prevent severe barrel leading.
