The casting itself was remarkably smooth, even with my initial setup. The molten lead flowed into the cavities of the two-cavity mold with satisfying completeness, filling out the detailed features of the bullet design. I found the process much faster than I had anticipated, partly due to the excellent heat retention of the Lyman mold itself. There were minimal defects, with only a few slightly underweight bullets that I attributed to my own learning curve with managing the lead flow and temperature, not an inherent flaw in the mold. The user feedback mentioning the speed of molding in half the time was immediately validated; this mold is efficient.

I tested the freshly cast bullets in a variety of conditions, primarily at an outdoor shooting range on a crisp autumn afternoon. The air was dry, and the temperature was moderate, which are ideal conditions for casting and shooting. My primary firearms for this test were a Smith & Wesson Model 686 and a Ruger Security-Six, both chambered in .357 Magnum but also very capable with .38 Special loads. I loaded them using standard load data for .38 Special, aiming for a pleasant shooting experience and to gauge the inherent accuracy of the cast bullet.

The ease of use was surprisingly high. While casting requires attention to detail and safety protocols, the mold itself is incredibly straightforward. The design is intuitive, and the instructions provided by Lyman are clear. The bullets dropped from the cavities with a gentle tap, and the sprue cut cleanly with minimal effort. The only initial surprise was the weight of the bullets – they felt substantial, confirming the “little on the heavy side” user feedback. However, this heft is precisely what I was looking for in certain .357 Magnum applications.

Extended Use & Reliability

After several months of consistent use, casting hundreds, if not thousands, of bullets with the Lyman Pistol Bullet Mould: 38/357 Caliber – #358311, its reliability and durability have become unquestionable.
