Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 Review

Using the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 in the Real World

For years, I’ve been chasing consistency and accuracy down at the reloading bench. The pursuit of that perfect round, one that whispers down the barrel with predictable precision, is what drives many of us who reload our own ammunition. My current obsession has been maximizing the potential of the venerable 7mm Remington Magnum, a caliber renowned for its power and range, but one that demands attention to detail to truly shine. This is where the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 entered my workshop. It promises a novel approach to neck sizing, aiming for unparalleled concentricity and case longevity.

What led me to this specific product was a desire to move beyond conventional sizing die methods that often overwork case necks. I was experiencing minute variations in neck tension and felt that the standard expander button was a potential point of inconsistency. My goal was simple: find a method that reliably sized the case neck just enough for a snug fit without unnecessary stress, thereby extending the life of my precious brass.

Upon receiving the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720, my initial impressions were, as is typical with Lee Precision products, utilitarian. The set arrived in a sturdy, no-frills plastic box, which is practical for storage but not exactly glamorous. The components themselves exude an air of functional simplicity. The dies are weighty and clearly made of durable metal, with a no-nonsense finish. The shellholder, a critical piece of the puzzle, felt solid and well-machined.

In my consideration process, I briefly looked at higher-end neck sizing dies from other manufacturers, some costing several times more. However, Lee’s reputation for delivering effective, well-engineered solutions at accessible price points, coupled with the specific design of the collet die, ultimately swayed my decision. I was cautiously optimistic, hoping this tool would deliver on its promise of superior neck tension control.

My first impression was one of anticipation. The design was different from anything I’d used before for neck sizing, and I was eager to see how this collet-based system would perform in practice. The weight and solid feel of the dies suggested they were built to last, but the real test would be how they translated that solidity into precise ammunition.

Real-World Testing: Putting Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 to the Test

First Use Experience

My first real encounter with the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 happened on my dedicated reloading bench, a space meticulously organized for efficiency and accuracy. The setup process was straightforward, requiring me to mount the collet die and seating die into my press and insert the included shellholder. The initial test batch involved about twenty pieces of once-fired 7mm Remington Magnum brass that had previously been fired in my rifle.

The actual operation of the collet die was quite different from a standard neck sizing die. Instead of an expander plug pushing through the neck, a collet clamps down, squeezing the brass onto a mandrel. This felt inherently more controlled. I noted that the die needed a bit of attention before it ran smoothly. As the user feedback hinted, a quick disassembly and a gentle polish of the collet’s interior surfaces made a noticeable difference in the smoothness of operation.

I found that applying a very light coat of dry graphite lubricant to the collet itself significantly improved the feel and prevented any sticking. This is a small step, but one that’s crucial for consistent results. Without this, there was a slight grittiness to the pull, which I wanted to eliminate entirely for maximum precision.

During this initial use, I discovered that the dead length seating die was also a welcome addition to the set, ensuring consistent seating depth, which is paramount for accuracy. Overall, the first use was a learning experience, highlighting the minor but important tweaks that can optimize the performance of precision tooling.

Extended Use & Reliability

Weeks turned into months, and this Lee die set has become a staple in my 7mm Remington Magnum reloading process. It’s seen regular use, not just for one-off batches, but for developing loads and then producing consistent ammunition for target practice and occasional hunting trips. The cases that have gone through this collet die consistently show minimal stress marks around the neck, and the cases themselves seem to be lasting considerably longer than when I used a conventional full-length or neck sizing die.

Durability has been excellent. Despite being repeatedly cycled through my press and occasionally subjected to the inevitable bumps and scrapes that happen in a busy workshop, the dies show no signs of wear that would affect their function. The collet mechanism remains precise, and the seating die continues to deliver bullets with minimal runout. I haven’t noticed any degradation in performance over time, which speaks volumes about the build quality.

Maintenance is refreshingly simple. A quick wipe-down with a soft cloth after use is usually sufficient. The ability to easily disassemble the collet die for cleaning or polishing, as I did initially, is a significant advantage for any reloader who values pristine tools. I’ve encountered no issues with rust or corrosion, even in my relatively humid workshop. Compared to some more complex die systems I’ve used in the past, this Lee set requires very little fuss to keep it in top working order.

Breaking Down the Features of Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720

Specifications

The Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 is a comprehensive package designed for precision handloading. It includes a collet neck sizing die, a dead length bullet seating die, and a corresponding shellholder. Crucially, it also contains a powder measure, a charge table, and a storage box, making it a truly all-in-one solution for someone starting to reload a specific caliber.

The primary benefit of the collet neck sizing die is its method of resizing. Instead of an expander plug, it uses a precisely machined collet that grips the outside of the case neck. This collet then squeezes the neck down onto a hardened steel mandrel, ensuring consistent neck diameter and an exceptionally low runout. This method is particularly beneficial as it avoids stretching the brass excessively, leading to greater case life and more uniform neck tension.

The dead length bullet seating die is engineered to seat bullets to a consistent depth relative to the case head, rather than the shoulder. This is vital for maximizing accuracy, especially when seating bullets out to kiss or lightly engage the rifling. The included shellholder is specific to the 7mm Remington Magnum cartridge family, ensuring a proper fit and reliable extraction.

Performance & Functionality

At its core, the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 excels at its primary function: producing accurate and consistent ammunition. The collet neck sizing die delivers on its promise of controlled neck tension. I’ve observed significantly reduced runout in my sized cases compared to previous methods, which directly translates to more stable bullet flight and tighter groups downrange.

The dead length seating die is equally impressive. It consistently seats bullets to the same depth, eliminating a common variable that can wreak havoc on accuracy. This precision is especially noticeable when pushing the limits of cartridge overall length (COL) to optimize for magazine length or barrel freebore.

The included powder measure is a functional, if basic, tool. It provides reasonably consistent charges, though for the absolute highest levels of precision, many reloaders opt for a more sophisticated, micrometer-adjustable powder measure. However, for general use and for someone getting started, it’s a perfectly adequate component that adds significant value to the set. The charge table is a helpful reference, though always remember to cross-reference with up-to-date load manuals.

Design & Ergonomics

The design of this die set is purely functional, prioritizing performance over aesthetics. The metal used for the dies is robust and provides a satisfying weight, giving a sense of durability. The knurled surfaces on the dies offer good grip, even with slightly greasy hands, which is a practical consideration during extended reloading sessions.

Ergonomically, the dies are designed to work seamlessly with most standard reloading presses. The dead length seating die features a convenient seater adjustment screw that allows for fine-tuning of bullet depth. The collet die, while requiring a bit more force than a standard neck sizer due to the collet action, operates smoothly, especially after the initial polishing. The included shellholder fits snugly and operates reliably.

Durability & Maintenance

In terms of durability, this set is built to last. The solid construction of the dies suggests they can withstand years of heavy use. The collet mechanism, being the most intricate part, has held up exceptionally well. Lee Precision generally uses hardened steel for its critical components, which contributes to their longevity.

Maintenance is straightforward. As mentioned, a light application of graphite or dry lube on the collet and mandrel is beneficial. Periodically, it’s wise to check the threads where the dies screw into the press and ensure they are clean. Disassembly for cleaning is simple; the collet just needs to be unthreaded from the die body. This ease of maintenance is a significant advantage for anyone who values their reloading tools.

Accessories and Customization Options

The Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 is notable for its completeness. The inclusion of the powder measure, charge table, and storage box means that a reloader has the fundamental tools to start producing ammunition immediately after acquiring appropriate case prep equipment and bullets. The storage box is a basic but effective way to keep all the components organized and protected.

While the dies themselves are caliber-specific, the powder measure is a general-purpose tool that can be used for other calibers with appropriate bushings (though bushings are not included with this specific set). The dead length seating die allows for precise adjustment of bullet seating depth, offering a degree of customization for load development. There are no real “customization options” for the dies themselves, as they are designed for a specific purpose, but their effectiveness in achieving precise neck tension and bullet seating can be seen as a form of performance customization for your ammunition.
