The Lyman Rifle Mould Single Cavity 45 Cal 405gr (SKU: LY-M40193, also associated with manufacturer code 2640193) is a precision-engineered bullet casting tool designed for handloaders who demand consistency and historical accuracy. This single-cavity mold produces the classic #457193 bullet design, which is the original 405-grain flat-nose projectile historically loaded in the venerable .45-70 Government cartridge. Crafted from solid leaded-steel, the mold blocks are precision-machined to a smooth, super-fine finish. Unlike aluminum alternatives, the steel construction provides superior heat retention, ensuring stable casting temperatures and highly consistent bullet diameters and weights throughout long casting sessions.
Key Features:
- Solid Leaded-Steel Blocks: Offers exceptional durability and thermal mass, maintaining optimal casting temperatures for uniform bullet release and minimal weight variance.
- Historical Bullet Profile: Casts the authentic 405-grain flat-nose bullet, replicating the original ballistics and appearance of classic .45-70 Government ammunition.
- Lever-Action Safety: The flat-nose (FN) profile is specifically designed to prevent accidental primer detonation when cartridges are stacked end-to-end in tubular magazines.
- Precision Machining: Exacting tolerances ensure clean parting lines, reducing flashing and post-cast processing time.
- Single-Cavity Design: Allows the caster to focus on maximum quality control and consistency for each individual projectile.

Who It Is For:
The Lyman LY-M40193 is designed for dedicated Australian handloaders, historical firearms enthusiasts, and competitive shooters. It is highly suited for Black Powder Cartridge Rifle (BPCR) silhouette competitors and target shooters who require extreme consistency in their projectiles. Hunters using classic lever-action rifles chambered in .45-70 Government—such as Marlin 1895 or Winchester 1886 models—will find the flat-nose profile essential for safe tubular magazine feeding. As a mechanical, non-electrical reloading tool, this mold is fully compliant for import and use across all Australian states. To operate this mold, users will require standard Lyman mold handles and a suitable lead melting pot.
