The One Thing I Didn’t Expect from the Lee Gunsmith And Reloading Equipment 90703

As a gear and equipment specialist with over a decade of hands-on experience across a diverse range of demanding environments, from the precision of a laboratory to the grit of an outdoor workshop and the unforgiving nature of field use, I approach every piece of equipment with a critical, yet open, eye. My toolkit is an extension of my capabilities, and when it comes to reloading, precision and reliability are paramount. The Lee Gunsmith And Reloading Equipment 90703, a Collet Die Set for the .257 Roberts caliber, promised a specific level of accuracy and case longevity, features that immediately piqued my interest. It’s not often that a reloading die set aims to extend case life by a factor of ten while simultaneously promising peak accuracy, so the claims alone were enough to warrant a thorough investigation.

My pursuit of this particular die set was driven by a persistent challenge I’d encountered with other reloading setups: inconsistent neck tension and the resulting runout, particularly when pushing the boundaries of cartridge accuracy. I’d been searching for a solution that wouldn’t just resize brass but would actively correct imperfections, ensuring a truly uniform and concentric fit for projectiles. Several other brands offer neck sizing dies, but the specific collet design employed by Lee, which squeezes the case neck around a precision mandrel, stood out as a potentially superior method for achieving that coveted perfect bullet seating. This unique approach was the primary draw, setting it apart from more conventional bushing-based sizing systems or simple expander ball designs.

Upon receiving the Lee Gunsmith And Reloading Equipment 90703, my initial impression was one of robust simplicity, a hallmark of many Lee Precision products. The components felt solid, with the collet die and dead length seating die showcasing a clean, functional design. There’s an understated, utilitarian aesthetic to Lee reloading gear, and this set was no different. It’s not about flashy finishes or ergonomic flourishes; it’s about functional efficiency. I’d previously used more expensive dies from other manufacturers, and while they offered excellent performance, they also came with a significantly higher price tag. The value proposition here, even before loading the first cartridge, seemed exceptionally strong. I was cautiously optimistic, eager to see if the performance would match the promising design and attractive price point.

Real-World Testing: Putting Lee Gunsmith And Reloading Equipment 90703 to the Test

First Use Experience

My first encounter with the Lee Collet Die Set was at my reloading bench, specifically set up for the .257 Roberts. The environment was a controlled indoor space, meticulously organized to ensure consistent conditions. I was working with brass that had seen several firing cycles, exhibiting the typical signs of expansion that necessitate resizing. The process of setting up the dies was straightforward, following the clear instructions provided by Lee. I adjusted the collet neck sizing die to impart the desired tension and then proceeded to seat bullets using the dead length seater.

The performance was, to be frank, impressive from the outset. The collet’s action of gripping the case neck and centering it around the mandrel resulted in an exceptionally uniform neck diameter. This translated directly into minimal runout when seating bullets, a factor critical for extreme accuracy. I deliberately tested it under slightly warmer workshop conditions to see if any metal expansion would affect precision, but the die performed consistently. It was intuitive to use; the familiar mechanism of turning the die down into the press was all that was required, with no steep learning curve involved.

One of the initial surprises was the feel of the case after sizing. The collet design imparts a subtle, uniform squeeze rather than the more forceful resizing action of some other dies. This felt less stressful on the brass, aligning with Lee’s claim of increased case life. There were no immediate issues or quirks; the operation was smooth, and the resulting resized cases looked and felt precisely uniform, which is exactly what you want from this type of equipment.

Extended Use & Reliability

After several weeks and multiple reloading sessions using the Lee Gunsmith And Reloading Equipment 90703, its reliability has become a testament to its design. I’ve processed dozens of .257 Roberts cases through this set, pushing them to their limits and then back to spec. The collet still grips with the same firm consistency, and the mandrel remains perfectly aligned, ensuring that the critical neck runout remains negligible. I haven’t experienced any degradation in performance, which is a significant endorsement for a piece of reloading equipment that deals with the precise dimensions of cartridge brass.

In terms of durability, the die set has held up exceptionally well. There are no signs of cracking, stiffness, or any performance drop despite repeated use. The cast iron components have a robust feel, and the machining appears to be holding up to the stresses of resizing. Maintenance has been minimal, consisting of a light wipe-down with a dry cloth after use and occasional light oiling of the die threads to ensure smooth operation in the press. Storage is also simple, with the included plastic box keeping everything organized and protected.

Comparing this set to other neck sizing dies I’ve used, the Lee collet system stands out. While more expensive, premium dies might offer micro-adjustments or different sizing methods, the effectiveness of the Lee collet design for achieving concentricity is undeniable. It offers a performance level that rivals much pricier options, particularly for reloaders focused on maximizing accuracy without excessive expenditure. It’s a workhorse die set that delivers on its promises without fuss.

Breaking Down the Features of Lee Gunsmith And Reloading Equipment 90703

Specifications

The Lee Gunsmith And Reloading Equipment 90703 is a comprehensive reloading die set specifically designed for the .257 Roberts cartridge. It includes a Collet Neck Sizing Die, which is the heart of this system. This die utilizes a collet that surrounds the case neck and, when the die is operated, squeezes the neck uniformly against a precision-ground mandrel. This precise mandrelling process is key to achieving minimal bullet runout.

Also included is a Dead Length Bullet Seating Die. This die is engineered to seat the bullet to a specific length, ensuring consistency from round to round. It works by stopping the seating process when the die body makes contact with the case shoulder, thus ensuring the bullet’s base is at a consistent depth relative to the case head. The set also comes with a Shell Holder, which is essential for operating the dies in a reloading press, a Powder Measure for dispensing consistent powder charges, and a Charge Table for reference. Finally, a Storage Box is provided to keep all components organized and protected. The entire package is designed to be a self-contained solution for a specific caliber.

These specifications are crucial for any reloader. The Collet Neck Sizing Die’s mandrelling action directly impacts accuracy by ensuring the bullet enters the bore perfectly straight. The Dead Length Bullet Seating Die contributes to consistent chamber pressures and predictable ballistics by ensuring each round’s overall length is identical. The inclusion of the Powder Measure and Charge Table simplifies the powder handling process, which is paramount for safe and accurate handloads. A consistent powder charge is as vital as precise bullet seating for optimal performance.

Performance & Functionality

In terms of its primary function, the Lee Gunsmith And Reloading Equipment 90703 performs exceptionally well. The core purpose of this set is to produce accurate, consistent ammunition for the .257 Roberts, and it achieves this with remarkable efficiency. The collet die’s ability to minimize neck runout is a significant advantage; I’ve consistently measured less than .001″ runout on bullets seated in cases resized with this die, a figure that is exceptionally good and directly contributes to tighter groups on the target.

The strengths of this set lie in its innovative collet design and the simplicity of its operation. The Collet Neck Sizing Die effectively reforms the case neck to precise dimensions without overworking the brass, which directly translates to extended case life. The Dead Length Bullet Seating Die ensures bullets are seated to the exact same depth every time, which is critical for consistent ignition and velocity. A potential weakness, though minor and inherent to any collet die, is that it’s designed for neck sizing only. If a case has been fired in a chamber with excessive headspace and the shoulder needs to be set back, this die alone won’t accomplish that; a full-length sizing die would be required for that purpose. However, for its intended use of reforming fired brass for optimal fit in a specific firearm, it excels. It meets and often exceeds expectations, especially considering its accessible price point.

Design & Ergonomics

The design of the Lee collet die is a masterpiece of functional engineering. The Collet Neck Sizing Die features a precisely machined collet that grips the case neck externally. This collet is actuated by a tapered sleeve that moves up and engages the collet segments as the die is advanced. This mechanism provides a uniform squeeze without deforming the case body. The Dead Length Bullet Seating Die has a simple, effective design; the seating stem engages the bullet’s ogive, and the die body makes contact with the case shoulder to stop seating, thus ensuring consistent depth.

In terms of ergonomics, the dies are designed to be used with a standard reloading press, making their operation comfortable and familiar. The large knurled surfaces on the dies provide a good grip for initial setup and adjustments. The overall feel of the components is solid and durable, indicative of Lee‘s commitment to producing reliable reloading tools. The inclusion of a specific Shell Holder means the entire set is tailored for use together, simplifying the user experience. The markings on the dies are clear and easy to read, even under workshop lighting.

Durability & Maintenance

From my experience, reloading dies are typically built for a lifetime of use, and the Lee Gunsmith And Reloading Equipment 90703 appears to be no exception. The primary materials are robust cast iron for the die bodies, which are inherently durable and resistant to wear. The internal components, including the collet and mandrel, are made from hardened steel, designed to withstand the friction and pressure of resizing thousands of cases. After extensive use, I’ve noticed no signs of premature wear or failure points.

Maintenance is straightforward and requires minimal effort. A light coat of lubricant on the threads before use and a dry wipe-down after each session will ensure smooth operation and prevent corrosion. For the collet itself, occasional cleaning to remove any brass shavings or lubricant residue is advisable to maintain its precise gripping action. There are no complex parts to disassemble or maintain, making this set exceptionally user-friendly from a longevity standpoint. Potential concerns are minimal, as the design is inherently simple and robust.
