The RCBS Bullet Mould 45-255-SWC (Model R82050) is a premium, manually operated double-cavity casting tool engineered for precision handloaders. Machined from solid, high-density cast-iron blocks, this mould is built to drop highly consistent 45-caliber Semi-Wadcutter (SWC) projectiles. Operating as a purely mechanical hand tool, it requires no electrical power, making it fully independent of local voltage configurations. It provides custom handloaders with a reliable means of producing uniform projectiles that deliver deep penetration and clean-cut holes in paper targets.

Key Features of the RCBS Bullet Mould 45-255-SWC

• Precision-Ground Cast-Iron Blocks: Machined from high-density cast iron that is ground square prior to cavity machining, providing superior heat retention and structural longevity compared to aluminum alternatives.
• Alignment Integrity: Built with heavy-duty steel alignment pins to guarantee a perfect face-to-face block mate, eliminating casting seams and flashing on your finished projectiles.
• Clean-Shearing Sprue Plate: Features a 3/16-inch-thick solid steel sprue plate held tightly against the cast-iron blocks to clean-shear the bases of the cast bullets.
• Semi-Wadcutter Profile: Cuts clean, circular holes in paper targets and provides excellent energy transfer and penetration for hunting applications.

Who is the Rcbs Bullet Mould 45-255-Swc for?

• Handloaders casting projectiles for .45 Colt revolvers — benefit from this double cavity bullet mould which drops custom projectiles at a nominal .454" diameter and 255-grain weight, allowing reloaders to size the cast lead down to .452" to match their specific cylinder throats.
• Handloaders casting projectiles for lever-action rifles — require the flat-nosed 0.33" meplat diameter produced by this double cavity bullet mould, which ensures the loaded .45-caliber cartridges can safely stack nose-to-tail in tubular magazines without risk of accidental primer ignition.

Less suitable for: high-volume casting sessions exceeding 500 projectiles per session, where a high-production caster setup, such as a 4-cavity or 6-cavity aluminum or brass mould, is more suitable to reduce hand fatigue and increase hourly output.
