Running the first few bullets was a learning curve; getting the right temperature balance between the lead and the mould is crucial. Too cool, and you get fill-out issues; too hot, and you risk lead sticking or porosity. However, the Lyman mould was forgiving, and with minor adjustments, I began to produce consistently well-formed bullets.

Ease of use is a significant factor, and this mould excels. The single cavity design simplifies the process for beginners, and the sprue plate operates smoothly, cleanly cutting the excess lead without requiring excessive force. The handles, though basic, offer a good grip and ample leverage to open and close the mould, which is essential for efficient casting. The only surprise was how quickly the mould heats up and maintains its temperature, a testament to its dense construction.

After that initial session, I moved to the shooting range with my custom-cast 370-grain Maxi-Ball projectiles. The real test of a mould isn’t just how well it casts, but how the cast bullets perform downrange. The Lyman-cast bullets, sized to match my barrel’s groove diameter, fed cleanly into the bore and loaded with consistent pressure. This consistency translated directly into tighter groups than I had ever achieved with store-bought alternatives.
