Rcbs Semi-Wadcutter Pistol Bullet Mould - Double Cavity .400" 200Gr
The RCBS Semi-Wadcutter Pistol Bullet Mould is a double-cavity casting tool built for handloaders who want consistent, quality cast bullets. This .400-inch mould produces 200-grain semi-wadcutter projectiles—a proven profile for target shooting, plinking, and handgun practice. If you're casting your own ammunition to reduce cost per round and fine-tune your loads, a quality bullet mould is the foundation of the job, and RCBS has been manufacturing reloading equipment for over 60 years.
Cast from solid iron blocks precision ground square and fitted with steel alignment pins, this mould delivers repeatable castings shot after shot. The two-cavity design means you're producing bullets in pairs, speeding up your casting sessions compared to single-cavity moulds. The sprue plate is machined from solid steel and clamped securely with tempered steel screws and spring washers—hardware built to handle the thermal cycling of hot lead without creep or shift.
Whether you're loading for a .40 S&W, 10mm, or another cartridge that feeds semi-wadcutter pistol bullets, this mould fits into a serious handloader's toolkit. Cast bullets offer savings and customization that factory ammunition can't match, and starting with proven RCBS equipment means fewer casting variables to troubleshoot.

Frequently Asked Questions
What calibers can I use this .400-inch semi-wadcutter mould for?
The .400-inch bullet diameter is suitable for cartridges like the .40 S&W and 10mm Auto. Always verify that your specific cartridge and load combination is compatible with cast bullets before loading, and consult published reloading data for your chosen caliber.
Is this mould suitable for a beginner bullet caster?
Yes. RCBS moulds are designed for reliable, repeatable results. If you're new to casting, a double-cavity mould like this one offers a good balance: faster than single-cavity production without overwhelming complexity. Start with quality casting alloy and follow best practices for pouring temperature and mould preheating.
What does the double-cavity design mean for my casting speed?
A double-cavity mould produces two bullets per pour instead of one, effectively doubling your production rate compared to a single-cavity mould. This significantly reduces the time needed to cast a batch of ammunition.
What equipment do I need to use this bullet mould?
This mould is the casting block itself. You'll need a lead melting pot, ladle or casting pump, proper ventilation, casting alloy (lead-tin or published bullet-casting alloy), and a mould handle to secure the mould during pouring. Never use this mould without a handle, and always follow safe lead-handling and casting practices.
