The Lyman Single Cavity Bullet Mould 358439Hp is a precision casting tool built for handloaders who want to cast .38 and .357 caliber bullets at their own pace. This single-cavity mould produces 155-grain hollow point flat nose (HPFN) projectiles—a classic design favored by shooters who reload for .38 Special, .357 Magnum, and compatible platforms. If you're serious about cost-effective ammunition production and want consistent, quality bullets cast to your exact specifications, a single-cavity mould like this one rewards patience with reliable results and total control over your handloading process.
Lyman has built its reputation on moulds that perform reliably over thousands of castings. This single-cavity design is ideal for the methodical reloader who prioritizes precision over speed, or for anyone looking to experiment with load development without the commitment of a larger cavity block. The 155-grain HPFN profile is a proven weight and configuration for both target shooting and defensive loads in the .38/.357 family.
Whether you're refining your handloading setup, casting bullets for a specific load development project, or simply want a dedicated mould for a particular bullet weight and profile, this Lyman single-cavity tool delivers the accuracy and durability you'd expect from a manufacturer that's been the standard in the casting world for decades.

Yes. Single-cavity moulds are often recommended for newer reloaders because they're easier to manage, require less lead at a time, and help you develop good casting technique before moving to multi-cavity blocks.
