What specific bullet does this mould cast, and what are its key characteristics?

This mould casts the historic "Gould Express" bullet (#457122), a 330-grain, .45 caliber flat-nose hollow-point (FN HP) projectile. It is renowned for its devastating expansion and energy transfer, making it an excellent choice for large game hunting.

What types of firearms and hunting applications is the "Gould Express" bullet best suited for?

The "Gould Express" bullet is primarily designed for high-performance hunting in .45 caliber rifle cartridges, most famously the .45-70 Government. Its hollow-point, flat-nose design provides excellent terminal ballistics for large game, suitable for both vintage and modern rifles, as well as black powder cartridge rifles.

What additional accessories are required to use this Lyman bullet mould?

To effectively use this mould, you will need Lyman standard hardwood mould handles, which are not included. Additionally, for precise sizing of your cast bullets, the Lyman Top Punch #191 (Part #2786701) is required.

Does this bullet mould have any specific electrical requirements or Australian certifications?

No, this Lyman bullet mould is a purely mechanical, non-powered hand tool used for casting molten lead. It does not contain any electrical components, heating elements, or wiring, so Australian 240V electrical standards or SAA/RCM certifications are not applicable.

What cartridges is this .45 caliber mould compatible with, and are there any recommended storage solutions?

This mould is highly compatible with .45 caliber rifle cartridges, most notably the .45-70 Government, and can also be used with black powder cartridge rifles. For safe and organised storage of your loaded .45-70 ammunition, the Plano Sturdy Safety Hard Plastic Ammo Box Rifle Medium (PL122950) is an excellent option.

How durable is this mould, and what maintenance is recommended for longevity?

This mould is machined from solid leaded-steel blocks and heat-treated to a blue finish for enhanced durability and reduced break-in time. Regular cleaning to remove lead residue and light oiling after use will ensure its longevity and continued precision casting.

.45 Caliber Bullet Mould - Lyman LY-M50122

The Lyman Mould Rifle Single Cavity 45 Cal 330 Gr (SKU: LY-M50122) is a premium-grade bullet casting tool designed to produce the historic "Gould Express" projectile (mould number #457122). Originally designed in the 1880s by John Barlow for A.C. Gould, this classic flat-nose hollow-point (FN HP) design is widely respected for its exceptional terminal performance. Machined from solid leaded-steel blocks, this mould is heat-treated to a blue finish, which reduces the traditional break-in period by up to half. As a purely mechanical hand tool, this product requires no electrical power, making Australian 240V electrical standards and RCM certifications non-applicable. It provides Australian handloaders with a reliable, high-precision method for casting custom .45 caliber ammunition.

Key Features:

Premium Steel Construction: Crafted from solid leaded-steel blocks and heat-treated to a blue finish, ensuring durability and reducing break-in time.
Precision Alignment: Features hardened steel alignment pins that ensure the two halves of the mould block align perfectly, maintaining consistent bullet concentricity over thousands of casts.
Clean Bullet Bases: Equipped with a ground-flat solid steel sprue plate held firmly by tempered steel spring washers and screws to ensure flat, clean bases on every cast.
Historic Gould Express Profile: Casts a 330-grain flat-nose hollow-point bullet that delivers devastating expansion and energy transfer on impact.
Single-Cavity Efficiency: The single-cavity configuration allows bullet casters to focus on maximum quality control and weight consistency for each individual projectile.
