Lyman Single Cavity Bullet Mould 358439HP 38/357 cal 155 gr HPFN

The Lyman Single Cavity Bullet Mould 358439HP in .38/357 caliber produces consistent 155-grain hollow point flat nose (HPFN) projectiles for handloaders serious about ammunition precision. Single cavity moulds are the choice for shooters prioritizing uniformity over production volume, allowing meticulous control of each round's weight and geometry—critical for accuracy-demanding applications like competitive shooting, duty ammunition development, and precision handloading.

This mould casts the 358439HP design, a proven bullet profile engineered for .38 Special and .357 Magnum platforms. The 155-grain weight delivers a balanced performance envelope—sufficient mass for reliable expansion in hollow-point applications while maintaining velocity stability across the spectrum of .38 and .357 loads. The flat nose geometry provides enhanced bullet-to-powder contact for consistent ballistics and reduces the risk of bullet setback during magazine feeding, a practical consideration for duty and defensive loads. Lyman single cavity blocks have established themselves as the baseline standard in pistol bullet casting, with tolerances and materials that support multiple generations of production without degradation.

Handloaders working with .38 Special target loads, cowboy action ammunition, and custom .357 Magnum defensive rounds rely on single cavity casting to achieve lot-to-lot consistency impossible with commercial bullets. The 358439HP serves competitive shooters, law enforcement ammunition specialists, and experienced reloaders who value the flexibility and cost efficiency of casting their own projectiles. Whether you're developing reduced-recoil loads for training, optimizing ballistic performance for duty weapons, or supporting high-volume practice sessions at a fraction of commercial ammunition cost, this mould delivers the repeatability required for serious handloading.
