What specific calibre and bullet weight does the Lyman LY-M60666 mould produce?

The Lyman LY-M60666 mould is engineered to cast 200-grain (gr) lead bullets specifically for the .44-40 Winchester (.44-40 WCF) calibre. The resulting bullet design is the #427666 profile, ideal for handloaders seeking precision for this classic cartridge.

Is this mould suitable for Cowboy Action Shooting, and what are its key design features for that purpose?

Yes, this mould is highly suitable for Cowboy Action Shooting (SASS). The #427666 bullet profile features a precisely positioned crimping groove, which ensures the loaded cartridge maintains the correct overall length for reliable feeding in both lever-action rifles and single-action revolvers chambered in .44-40.

What additional Lyman accessories are essential to use this double cavity mould?

To operate the Lyman Double Cavity Mould LY-M60666, you will need Lyman Double Cavity Mold Handles, which are sold separately. For post-casting processing, a sizing die compatible with a nominal bullet drop diameter of .427" to .428" is recommended, along with a Lyman Top Punch #649 (or #43), also sold separately.

What is the construction material of this Lyman mould, and how does it contribute to bullet consistency?

This Lyman mould is precision-machined from solid, heat-treated leaded-steel blocks. The blued finish helps minimise the break-in period and ensures clean, consistent bullet release, which is crucial for producing uniform projectiles with each cast.

Are there any specific Australian regulatory considerations for owning or importing this bullet mould?

This product is a purely mechanical, non-powered hand-casting tool, so Australian electrical certifications (like 240V or SAA/RCM) are not applicable. While bullet moulds are generally legal to own without a firearms license in most Australian jurisdictions, XHunter always recommends verifying local state and territory police regulations regarding reloading components.

Bullet Mould 44/40 200gr - Lyman LY-M60666

The Lyman Mould Double Cavity 44/40 200gr (SKU: LY-M60666) is a precision-engineered bullet mould designed for handloaders who cast their own lead projectiles for the classic .44-40 Winchester (.44-40 WCF) calibre. Machined from solid leaded-steel blocks, this mould undergoes a specialized heat-treatment process that blues the metal, which significantly reduces the break-in period and ensures a smooth, clean release of cast bullets. Featuring the specialized #427666 bullet design, this double-cavity mould allows reloaders to cast two identical 200-grain projectiles simultaneously, improving production efficiency while maintaining strict dimensional consistency.

Key Features:

Double-Cavity Cast Efficiency: Casts two 200-grain bullets at the same time, doubling production speed compared to single-cavity moulds.
Cowboy Action Bullet Profile: The #427666 bullet profile is designed with a properly positioned crimping groove, ensuring the loaded cartridge achieves the correct overall length (OAL) for reliable feeding in both lever-action rifles and single-action revolvers.
Solid Leaded-Steel Construction: Precision-machined to an ultra-fine finish, the heat-treated steel blocks resist warping and deliver exceptional thermal stability during long casting sessions.
Integrated Sprue Cutter: Features a durable, pre-installed steel sprue cutter that cleanly shears off excess lead, leaving a flat, uniform base on every projectile.
No Electrical Requirements: This is a purely mechanical, non-powered hand tool, meaning Australian electrical standards, SAA/RCM certifications, and 240V AS/NZS 3112 plug configurations are not applicable.
