What makes the 'Devastator' hollow point design of this Lyman mould unique for 9mm projectiles?

The Lyman #356637 "Devastator" design casts a highly accurate, deep hollow-point bullet. Its profile is renowned for excellent accuracy and reliable feeding characteristics, making it a preferred choice among target shooters, including those in IPSC disciplines. This mould consistently produces bullets weighing between 124 and 125 grains, depending on your chosen lead alloy mixture.

What additional equipment do I need to start casting bullets with this Lyman mould?

To effectively use the Lyman LY-M50637 mould, you will need Lyman single-cavity (or standard double-cavity) mould handles, which are sold separately. Additionally, a lead melting pot, such as a Lyman or Lee casting furnace, and suitable lead alloy are essential. For Australian users, if purchasing an electric melting pot, ensure it is a 220V–240V model fitted with an Australian plug.

Does this Lyman mould require any special electrical setup or Australian safety certifications?

No, the Lyman LY-M50637 mould is a purely mechanical, non-powered hand tool and does not contain any electrical components. Therefore, it is not subject to 240V AC compatibility, SAA/RCM safety certifications, or Australian AS/NZS 3112 plug requirements. However, any electric lead melting pot used in conjunction with this mould must be a 220V–240V model suitable for the Australian domestic grid.

Can this 9mm mould be used for casting bullets for other calibers besides 9mm Luger?

Yes, while primarily optimised for 9mm Luger (9x19mm), the .356" bevel-base bullet cast by this mould offers versatility. It can be sized and loaded for other .35-caliber cartridges such as .38 Super, 9x21mm, and .380 ACP. With careful reloading practices, it can even be used for .38 Special/.357 Magnum, provided the reloader accounts for the absence of a traditional crimping groove.

How should I care for this steel mould to ensure its longevity and consistent performance?

The Lyman LY-M50637 is constructed from durable, heat-treated leaded-steel blocks with a pre-oxidised finish, designed for long-term use. After each casting session, ensure the mould is thoroughly cleaned of any lead residue. Store it in a dry environment to prevent rust, and applying a light coating of a suitable rust preventative or lubricant, such as Hoppe's No.9 Moisture Displacing Lubricant (HPMDL), will further protect the steel surfaces during storage.

9mm Hollow Point Bullet Mould - Lyman LY-M50637

The Lyman Mould Single Cavity Pistol HP 9mm Cal 125 Gr (SKU: LY-M50637, MPN: 2650637) is a precision-engineered bullet casting mould designed for handloaders who require high-performance, heavy-weight 9mm hollow-point projectiles. Machined from solid leaded-steel, this single-cavity mould produces the renowned #356637 Devastator Round Nose Hollow Point bullet with a bevel base. Unlike standard aluminum moulds, these steel blocks undergo a specialized heat-treatment process that pre-oxidises the metal. This blued finish significantly reduces the break-in time and ensures clean, effortless bullet release during the casting process.

Key Features:

Devastator Hollow Point Profile: Casts a highly accurate, deep hollow-point projectile weighing between 124 and 125 grains, depending on the lead alloy mixture used. This design is highly regarded for its reliable feeding and consistent flight characteristics.
Premium Steel Construction: Machined from solid leaded-steel to an ultra-fine finish, offering superior thermal stability and durability over aluminum alternatives.
Precision Alignment System: Hardened steel alignment pins keep the mould blocks perfectly mated, while the flat-ground steel sprue plate is held under tension with tempered steel spring washers to prevent shifting.
Versatile Caliber Compatibility: With a nominal bullet diameter of 0.356 inches, the cast projectiles can be sized and loaded for 9mm Luger (9x19mm), .38 Super, 9x21mm, and .380 ACP. They can also be adapted for .38 Special and .357 Magnum loads.
Australian Casting Setup Compatibility: This is a purely mechanical, non-powered hand tool with no electrical components. For Australian reloaders setting up their casting bench, please note that any electric lead melting pots paired with this mould must be 220V-240V models fitted with a standard Australian AS/NZS 3112 plug to operate safely on the domestic grid.
