Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139 Review

Discovering the Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139: My Take

For over a decade, I’ve navigated the rugged terrain of outdoor and tactical gear, a journey that’s honed my instincts for what truly performs. The quest for authentic, reliable equipment is a constant, especially when it comes to the nuanced world of reloading for vintage firearms. It was this relentless pursuit that led me to the Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139.

My need was specific: to cast bullets for my collection of .50 caliber rifles, particularly those chambered in less common cartridges like the 50-70 and 56-50. Finding a mould that specifically caters to these historic platforms, while offering consistent results and the legendary quality Lyman is known for, felt like striking gold. This particular mould promised a 340-grain flat-nose projectile, a profile well-suited for these older firearms where bore tolerances can vary and reliable feeding is paramount.

Unboxing the mould was a tactile experience I’ve come to cherish. The substantial weight of the machined iron, the crispness of the mould cavity’s edges, and the precision fit of the sprue plate all spoke of quality craftsmanship. It felt solid, almost heirloom-quality, a stark contrast to some of the flimsier casting tools I’ve encountered over the years.

While direct competitors for this exact mould profile are scarce, I had considered several other Lyman offerings and some generic aftermarket moulds. What swayed me towards the #515139 was its specific design for the 50-70 and 56-50 calibers, rather than a more generic .50 caliber offering. The Lyman brand also carries a weight of history and trust in the reloading community that’s hard to ignore.

My initial impression was one of profound satisfaction. This wasn’t just another piece of gear; it was a key to unlocking the full potential of my historical firearms, promising a level of authenticity and performance that mass-produced ammunition simply can’t replicate. The anticipation of casting my own ammunition, tailored precisely for these venerable rifles, was palpable.

Real-World Testing: Putting Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139 to the Test

First Use Experience

My initial casting session took place in my dedicated reloading room, a space optimized for precision and safety. The temperature was a comfortable 70°F, ideal for consistent lead alloy melting. I preheated the mould on my electric pot, ensuring it reached optimal casting temperature before the first pour.

The mould performed admirably from the get-go, demonstrating excellent heat retention and consistent fill. Using a standard 1:20 tin-lead alloy, the bullets emerged with sharp edges and well-defined bases, a testament to the mould’s precise machining. The 340gr weight was consistently achieved, a crucial factor for load development.

Ease of use was a significant factor. The sprue plate moved smoothly, and the alignment pins ensured perfect closure every time. There was a minimal learning curve, mostly related to achieving the ideal pouring temperature and cadence for the single cavity #2640139.

The only surprise was how easy it was. After years of wrestling with sticky sprue plates or poorly aligned halves on lesser moulds, the Lyman #515139 felt like a well-oiled machine. This immediate success built confidence for subsequent casting sessions.

Extended Use & Reliability

After months of regular use, casting hundreds of bullets, the Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139 has proven itself to be an exceptionally reliable tool. The cast iron construction, while requiring proper care, shows no signs of pitting or degradation from repeated heating and cooling cycles.

Durability is clearly a strong suit. The mould cavity remains pristine, with no signs of lead adhering in a way that would affect bullet quality. Even with the occasional accidental bump or scrape, the solid iron construction feels remarkably resilient.

Maintenance has been straightforward: a quick clean with a brass brush after each casting session to remove any residual lead, followed by a light wipe with a fine oil to prevent rust. This simple routine has kept the mould in prime condition, ensuring consistent performance over time.

Compared to my previous experiences with other mould brands, this Lyman mould significantly outperforms them in terms of consistency and ease of use. It has become my go-to for any .50 caliber rifle needing authentic, hand-cast projectiles.

Breaking Down the Features of Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139

Specifications

The Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139 is engineered with specific historical firearms in mind. It’s designed for .50 Caliber projectiles, a critical specification for compatibility with rifles like the 50-70 and 56-50. The mould produces a 340 grain bullet, a weight that strikes a balance between ballistic performance and lead usage for these calibers.

The specified Top Punch #191 ensures proper seating and alignment during the casting process, contributing to bullet uniformity. Its designation as a Single Cavity #2640139 means it’s a straightforward, no-frills mould, prioritizing ease of use and consistent results over high-volume production. This is perfect for those who value quality over quantity in their reloading endeavors.

Performance & Functionality

The primary function of this mould is to cast accurate, reliable bullets for specific .50 caliber firearms, and it excels at this task. The 340gr Flat Nose (FN) design is ideal for single-shot rifles and lever-action repeaters common in the era these calibers were prevalent. It ensures good feeding in tubular magazines and provides sufficient surface area for reliable ignition with black powder or modern smokeless powders.

Its main strength lies in its consistent bullet diameter and weight, leading to predictable shooting performance. A minor weakness could be the single-cavity design for those needing to produce large quantities of ammunition quickly. However, for most enthusiasts of historical firearms, the pace is usually more deliberate, and this mould meets and exceeds expectations.

Design & Ergonomics

The build quality of this Lyman mould is, in a word, exceptional. Machined from solid iron, it feels substantial and durable in the hands. The design is classic and functional, with well-contoured handles (though separate handle grips are often purchased) that provide good grip when working with hot lead.

It is incredibly user-friendly, especially for those with basic knowledge of bullet casting. The alignment is precise, and the sprue plate mechanism is smooth. There’s virtually no learning curve for experienced casters, and even a beginner can quickly master its operation with a bit of practice.

Durability & Maintenance

This Lyman mould is built to last for generations. The solid iron construction is inherently durable and resistant to deformation. With proper care and maintenance, it will likely outlive the shooter.

Maintenance is minimal and straightforward. A light cleaning with a brass brush after each use and a thin coating of rust-preventative oil are all that’s needed. This simple regimen ensures the mould remains in top condition, ready for countless casting sessions without degradation of performance.

Accessories and Customization Options

The Lyman Rifle Bullet Mould: 50 Caliber – #515139 2640139 typically comes as the mould block itself. Lyman offers separate, heat-treated iron handles that securely attach to the mould halves, providing a comfortable and safe grip during casting. These handles are crucial for ergonomic casting and preventing burns.

While the mould itself isn’t customizable in terms of its core design, its compatibility with various bullet lubricants and sizing dies from Lyman and other manufacturers is excellent. This allows for fine-tuning the bullet’s performance after casting, ensuring optimal accuracy and fit within the specific firearm. The Top Punch #191 is integral to the casting process, ensuring the correct bullet profile and base formation.
