My immediate reaction was a sense of quiet anticipation, eager to see if this tool would resolve my bullet performance woes.

Real-World Testing: Putting Lee 90057 Lube & Sizing Kit One Kit .457 Standard 7/8″ X 14″ Threads to the Test

First Use Experience

My testing commenced on my dedicated reloading bench, a familiar space for equipment of this nature. I mounted the Lee 90057 Lube & Sizing Kit onto my reloader press, ensuring the standard 7/8″ x 14″ threads seated firmly. The process of pushing cast bullets through the sizing die, nose first, proved remarkably straightforward, requiring minimal familiarization.

The most striking aspect of the initial use was the speed and efficiency. Within minutes, I had processed a tray of newly cast bullets, each emerging uniformly sized and coated in a thin, even layer of lubricant. There were no unexpected quirks or issues; the kit performed precisely as described, delivering a satisfyingly consistent result right out of the box.

Extended Use & Reliability

After several weeks of regular use, processing dozens of bullets for various .45 caliber loads, this lube and sizing kit has proven its mettle. It has become an indispensable part of my reloading routine, consistently delivering well-lubricated and properly sized projectiles.

There are no visible signs of wear and tear on the die or the internal components; it maintains its performance without any degradation. Cleaning is as simple as wiping down the exterior and occasionally running a soft cloth through the die to remove any residual lubricant. Compared to my past experiences with separate sizing dies and manual lubing methods, this integrated Lee system is significantly more efficient and less prone to inconsistencies.

Breaking Down the Features of Lee 90057 Lube & Sizing Kit One Kit .457 Standard 7/8″ X 14″ Threads

Specifications

The Lee 90057 Lube & Sizing Kit One Kit .457 Standard 7/8″ X 14″ Threads is designed for the precise calibration of cast bullets. It features a .457 diameter sizing die, which is crucial for ensuring optimal fit within the bore of many .45 caliber firearms. The kit includes the necessary components to both resize and lubricate bullets in a single operation.

The standard 7/8″ x 14″ threads are a significant advantage, guaranteeing compatibility with virtually any modern reloading press. This universal threading means users won’t need specialized adapters or presses to integrate this kit into their existing setup. The nose-first feeding mechanism eliminates the need for specific nose punches, simplifying the process further. Additionally, the design automatically seats and crimps gas checks, a feature that streamlines an often fiddly step in bullet preparation.

Performance & Functionality

The primary function of this kit—sizing and lubricating cast bullets—is executed with impressive effectiveness. Each bullet emerges from the process with a uniform diameter, ensuring a snug yet not overly tight fit in the firearm’s chamber and bore. This consistent sizing is directly responsible for improved accuracy and reduced barrel leading.

The lubrication applied by the kit is an even, thin film that effectively coats the bullet’s bearing surfaces. This lubricant is crucial for preventing friction and leading, especially with lead alloy bullets fired at higher velocities. While the kit excels at its core tasks, it’s important to note that the effectiveness of the lubrication also depends on the quality of the lube used, which is purchased separately.

Design & Ergonomics

The design of the Lee 90057 Lube & Sizing Kit is inherently practical and user-focused. Its robust construction suggests durability and longevity, even under frequent use. The die’s threading is clean and precise, allowing for smooth engagement with reloading presses.

The nose-first feeding design is ergonomically sound, making it easy to orient bullets correctly without fumbling. The integrated system for capturing sized bullets in a special container is a thoughtful touch, preventing them from scattering. This attention to detail simplifies the workflow and reduces potential mess.

Durability & Maintenance

Built with sturdy materials, this lube and sizing kit is designed for the rigors of a reloading environment. I have observed no signs of corrosion, deformation, or reduced performance over my extended testing period. It feels like a tool that will last for many reloading sessions.

Maintenance is commendably straightforward. A quick wipe-down after use is usually sufficient, with occasional deeper cleaning of the die’s internal passages if a different lube is used or if debris accumulates. There are no complex parts to disassemble or maintain, which is a major plus for busy reloaders.

Accessories and Customization Options

The Lee 90057 Lube & Sizing Kit is a self-contained unit designed to perform its specific function without requiring numerous additional accessories. The key “accessory,” in a sense, is the appropriate lube stick, which must be purchased separately and inserted into the die.

While this kit itself is not directly customizable in terms of its core components, its standard 7/8″ x 14″ threads ensure broad compatibility with existing reloading press setups. This standardization is a significant benefit, meaning users don’t need to invest in specialized equipment to utilize this kit effectively. The included bullet capture container is a practical addition that enhances the user experience.

Pros and Cons of Lee 90057 Lube & Sizing Kit One Kit .457 Standard 7/8″ X 14″ Threads

Who Should Buy Lee 90057 Lube & Sizing Kit One Kit .457 Standard 7/8″ X 14″ Threads?

This kit is ideally suited for handloaders who cast their own bullets for .45 caliber firearms and are seeking to streamline their bullet preparation process. Reloaders who frequently shoot lead alloy bullets and want to ensure proper sizing and lubrication for optimal performance and barrel longevity will find this an invaluable tool. It’s particularly beneficial for those looking to improve accuracy and reduce leading without investing in separate, high-end lubing and sizing machines.

Individuals who do not reload or who primarily shoot jacketed bullets might not find this specific product necessary. Those with limited reloading bench space might appreciate its integrated functionality compared to separate, bulkier equipment. For those who have already invested in a reloading press, this kit represents a cost-effective upgrade to their bullet processing capabilities.
