Taking the Lyman Pistol Bullet Mould: 38/357 Caliber – #358665 for a Spin

For over a decade, my hands have been intimately familiar with the raw materials of ammunition reloading – the brass, the powder, the primers, and the projectiles. I’ve spent countless hours at the bench, meticulously crafting rounds for everything from plinking .22LR to potent .45-70 Government loads. Yet, there’s a particular magic to casting your own bullets, a satisfaction derived from shaping lead into the exact form you need. When the need arose for a reliable, accurate bullet design specifically for the ubiquitous .38 Special and .357 Magnum cartridges, my sights were set on a classic: the Lyman Pistol Bullet Mould: 38/357 Caliber – #358665. This mould promises a 158-grain projectile, a weight that has proven itself time and again as the sweet spot for these venerable calibers.

What truly drew me to the #358665 mould was its reputation and its design features. I needed a bullet that would perform exceptionally well in both revolvers and lever-action rifles, a common scenario for those who enjoy the versatility of the .38/.357 platform. The mention of a “bore-riding nose” immediately caught my attention; this feature is crucial for ensuring proper bullet alignment upon entering the barrel, which translates directly into enhanced accuracy. While other moulds exist, many are either too light, too heavy, or lack this essential alignment aid. I compared it mentally to other common Lyman designs and some custom moulds I’d encountered, but the proven track record and the specific bullet profile of the #358665 made it the clear choice for my needs.

Upon receiving the mould, the heft and precision of Lyman manufacturing were immediately apparent. The two-cavity block felt solid in my hands, a reassuring weight that speaks of quality materials and construction. The mould halves came together with a satisfying precision, with no discernible gaps or rough edges that might impede proper bullet formation. It arrived ready to go, needing only a good cleaning and preheating.

Breaking Down the Features of Lyman Pistol Bullet Mould: 38/357 Caliber – #358665

Specifications

The Lyman Pistol Bullet Mould: 38/357 Caliber – #358665 is a meticulously crafted piece of reloading equipment designed for serious shooters and handloaders. It is specifically engineered for the .38 Special and .357 Magnum calibers, two of the most popular revolver cartridges in existence. This mould features a two-cavity or four-cavity design, allowing for efficient production of bullets.

The primary specification is the bullet weight: a substantial 158 grains. This weight is a classic choice for .38 Special and .357 Magnum, offering a balance of manageable recoil, good penetration, and excellent accuracy. The mould is designed to cast bullets with a bore-riding nose, a crucial feature for ensuring proper alignment as the bullet enters the barrel. This leads to more consistent ignition and improved accuracy.

The specified top punch #495 is an integral part of the casting process, ensuring the base of the bullet is properly formed. The mould requires compatible double cavity handles (#2660665) or four cavity handles (#2670665), depending on the model purchased, which are sold separately. This is an important consideration for new buyers. Finally, the mould is designed to cast bullets suitable for sizing dies ranging from .357 to .360 inches, providing flexibility for various firearm tolerances and desired performance characteristics.

Performance & Functionality

The performance of bullets cast from the Lyman Pistol Bullet Mould: 38/357 Caliber – #358665 is nothing short of exceptional, especially considering its purpose and price point. The 158-grain weight, combined with the semi-wadcutter (SWC) profile and the crucial bore-riding nose, delivers remarkable accuracy in both handguns and rifles chambered for .38 Special and .357 Magnum. I’ve consistently achieved tight groups at 25 yards with revolvers and sub-2-inch groups at 100 yards with my lever-action rifle using bullets from this mould.

A key strength of this mould is its versatility.
