Real-World Testing: Putting Lyman Pistol Bullet Mould: 45 Colt – #452490 2660490 to the Test

First Use Experience

My first casting session with the Lyman Pistol Bullet Mould: 45 Colt – #452490 2660490 took place on a crisp autumn afternoon in my dedicated casting shed. I preheated the mould to optimal casting temperature using my Lee Precision pot, ensuring a smooth pour. The process was straightforward, with the mould handling the molten alloy with ease. The included instructions, though brief, were clear, and the need for double cavity handles, as noted, is crucial for efficient production.

The bullets emerged from the mould with a clean release, showcasing crisp edges and well-defined features. I specifically noted the weight of the cast bullets after they cooled. As the user feedback indicated, the weight was slightly higher than the advertised 255 grains, coming in closer to 262 grains with the applied gas check, which weighed approximately 8 grains. This was not a disappointment; my .45 Colt revolvers, particularly my trusty Ruger Blackhawks, thrive on heavier projectiles. The consistency from cavity to cavity was impressive, a testament to the mould’s precision.

Performance-wise, during this initial casting, I didn’t encounter any significant issues. The alloy flowed well, and the gas checks seated properly without any fuss. The only minor learning curve was the slightly increased effort required to remove the heavier, gas-checked bullets compared to lighter, plain-based designs. However, this was easily managed with a firm, controlled pull. The resulting bullets looked superb, ready for sizing and loading.

Extended Use & Reliability

Over several weeks and approximately 500 rounds cast, the Lyman Pistol Bullet Mould: 45 Colt – #452490 2660490 has proven its worth. Its reliability in consistently producing quality bullets has made it a go-to mould for my .45 Colt reloading bench.

Durability is clearly not an issue. The machined iron construction feels robust, and after hundreds of cycles, there are no discernible signs of wear on the mould faces or sprigging pins. Maintenance is as simple as it gets: a quick wipe-down with a brass brush after each casting session to remove any residual lead or flux, followed by a light application of mould release or a graphite lubricant. This simple care routine keeps the mould in excellent condition and ensures consistent casting performance.

Compared to other moulds in my collection, this Lyman offers a distinct advantage for specific applications. While lighter bullets are great for plinking or lower-velocity loads, the #452490 excels when a heavier, more robust projectile is desired. The gas check significantly reduces leading in my revolvers, allowing for longer shooting sessions without the constant worry of fouling. This reliability and performance, especially for those who push their .45 Colt loads a bit harder, makes it a superior choice for its intended purpose.
