Breaking Down the Features of Lyman Pistol Bullet Mould: 44/40 – #427666

Specifications

The Lyman Pistol Bullet Mould: 44/40 – #427666 is a meticulously designed piece of casting equipment. It’s specifically engineered for the .44-40 Winchester cartridge, a caliber rich in firearms history. The mould produces bullets weighing approximately 200 grains, a weight that strikes a critical balance for this cartridge, offering good penetration and controlled expansion, suitable for both pistol and rifle applications.

A key feature is the crimping groove, essential for securely crimping bullets in the case mouth, particularly in firearms that experience recoil, such as revolvers and lever-action rifles. This groove ensures that the bullet remains seated under recoil and aids in achieving consistent ignition. The mould is designed to work with Top Punch #43, which is integral to forming the bullet’s nose shape and ensuring consistent seating.

This mould is available in different configurations: a Double Cavity #2660666 and a Four Cavity #2670666. These options allow the caster to choose between a lower volume, more manageable casting session (double cavity) or a higher production rate (four cavity). Importantly, both configurations require compatible double cavity or four cavity handles, respectively, which must be purchased separately. The specified Sizing Die sizes range from .427 to .428, offering flexibility to match the specific needs of your firearm’s bore dimensions. This range is critical for achieving a proper gas seal and ensuring accurate bullet flight.

Performance & Functionality

In terms of performance, the Lyman Pistol Bullet Mould: 44/40 – #427666 absolutely excels at its intended purpose. It consistently produces bullets that are dimensionally accurate and uniform in weight, which are the cornerstones of accurate handloaded ammunition. The 200-grain weight, coupled with the crimping groove, makes it incredibly versatile for the .44-40.

The crimping groove is perfectly positioned and sharp, allowing for a solid mechanical lock of the bullet in the case. This is crucial for Cowboy Action Shooting and general-purpose loads where bullet pull is a concern.
