The Lyman Mould Double Cavity 9mm 147gr (SKU: LY-M60637) is a precision-engineered bullet casting mould designed for handloaders who require high-quality, heavy-weight 9mm projectiles. Machined from solid leaded-steel blocks, this mould undergoes a specialised heat-treatment process that pre-blues the metal. This pre-bluing process minimises the initial break-in period and ensures a smooth, clean release of cast bullets. Featuring Lyman design number #356637, this double-cavity block allows reloaders to cast two uniform bullets simultaneously, significantly increasing casting efficiency.

Key Features:

  • Precision Steel Blocks: Crafted from solid leaded-steel and machined to an exceptionally fine finish for highly consistent bullet weight and dimensions.
  • Pre-Blued Finish: Heat-treated to oxidise the metal, reducing the break-in time and preventing lead from sticking to the cavity faces.
  • Integrated Sprue Cutter: Equipped with a hard-wearing, durable steel sprue cutter that cleanly shears off excess lead, leaving a flat, uniform bevel base on each projectile.
  • Double Cavity Design: Casts two 147-grain bullets per cycle, doubling production speed compared to single-cavity moulds.
  • Mechanical Operation: This product is a purely mechanical casting block and does not contain electrical components. For Australian handloaders, this means no electrical safety compliance (such as 240V or RCM certification) is required for the mould itself, though an Australian-compliant 240V lead melting furnace is required to melt the casting alloy.

Who It's For:

  • IPSC and Action Pistol Shooters: This mould is highly suitable for competitive handgun shooters in Australia who need to reliably meet "Minor" power factor requirements. The heavy 147-grain weight allows shooters to achieve the necessary power factor with lower velocities, resulting in reduced felt recoil, faster recovery between shots, and consistent downrange accuracy.
  • High-Volume Reloaders: Perfect for handloaders looking to control their projectile supply and reduce ammunition costs by casting their own custom-sized 9mm projectiles from lead alloy.
