What to Expect from the LEE 90813 COLLECT CRIMP DIE 357 MAG
For those of us who push the boundaries of cartridge reloading, especially for .357 Magnum, finding the right tooling can be a game-changer. The LEE 90813 COLLECT CRIMP DIE 357 MAG is one such tool that promises a robust solution for a specific, albeit common, reloading challenge. This die is particularly adept at ensuring bullet retention in heavy recoiling handgun cartridges, a scenario I’ve encountered numerous times on the bench and at the range. My own search for a more reliable crimp on certain loads, especially those using cast bullets, led me to this particular die from Lee.
Upon first inspection, the die feels solid and exhibits the no-nonsense utilitarian design that Lee is known for. It’s not about flashy aesthetics; it’s about delivering a specific function effectively. I considered other brand dies, but the unique “collect crimp” mechanism described in the product literature piqued my interest as a potentially more aggressive solution than standard crimpers. My initial impression was one of quiet competence—this die looked like it was built to do a job and do it well, without fuss.
Real-World Testing: Putting LEE 90813 COLLECT CRIMP DIE 357 MAG to the Test
My initial testing of the LEE 90813 COLLECT CRIMP DIE 357 MAG took place on my dedicated reloading bench, a space that’s seen everything from delicate match-grade rounds to brute-force hunting loads. The specific scenario that prompted this purchase was an ongoing issue with bullet pull on some .357 Magnum loads intended for a heavier revolver, where recoil was consistently trying to push bullets deeper into the case. I wanted a die that could provide a more tenacious grip than a standard taper or roll crimp, and the description of this die’s ability to “form a crimp groove if one is not present” was particularly compelling.
The die installed smoothly into my press, a process that is standard for most reloading dies. I adjusted the seating depth and crimp pressure incrementally, starting with lighter settings and gradually increasing them as I gauged the results. My first few test rounds were with some .38 Special cases loaded with cast lead bullets that lacked a distinct crimp groove, and I was keen to see if the die could indeed create that secure seating. What surprised me was the ease with which the die began to impart a significant crimp, even at relatively low settings. There was no real learning curve; the adjustment wheel provided tactile feedback, and the process felt intuitive.
After several weeks and several hundred rounds processed through this collect crimp die, its reliability has become a cornerstone of my .357 Magnum reloading. The die consistently applies a strong, uniform crimp, which has effectively eliminated the bullet-pull issues I experienced previously. I’ve used it on jacketed bullets and various cast alloy bullets, some of which were intentionally designed without deep crimp grooves to test the die’s stated capabilities. In every instance, the crimp held fast.
Durability has been excellent. There are no visible signs of wear, such as scoring on the internal die surfaces or deformation of the adjustment mechanism. It’s a simple, robust design. Maintenance is straightforward; a quick wipe-down with a cloth and a bit of lubricant during reloading sessions is all that’s needed. Compared to some other crimping dies I’ve used over the years, particularly those with more complex adjustment mechanisms, this Lee die feels more durable and less prone to developing issues. It’s a workhorse that requires minimal fuss.
First Use Experience
The first time I locked the LEE 90813 COLLECT CRIMP DIE 357 MAG into my press, it was during a batch of .357 Magnum loads designed for a particularly potent load. I was experiencing a persistent problem with bullet jump under heavy recoil, and standard crimps just weren’t cutting it anymore. My aim was to find a solution that would secure the bullet firmly, without deforming the case or the bullet excessively.
I was working on my bench, under good lighting, with a steady supply of prepped brass and projectiles. The die installed without any fuss, and the adjustment was straightforward, allowing me to dial in the desired crimp pressure. My initial test rounds were with cast bullets that had a relatively shallow crimp groove, and I was curious to see how the die would handle this. The first few rounds came out with a noticeably aggressive crimp, and the bullet felt exceptionally well-seated. There were no surprises or unexpected quirks; it performed exactly as described from the outset.
Extended Use & Reliability
Over the course of several reloading sessions, spanning weeks and hundreds of rounds of both .357 Magnum and some .38 Special loads, the LEE 90813 COLLECT CRIMP DIE 357 MAG has proven itself to be remarkably consistent. The crimp it applies remains uniform across batches, and I haven’t encountered any variations in performance. This consistency is crucial for handloaded ammunition, where predictable performance is paramount.
I’ve run the die through its paces with various bullet weights and profiles, including some slightly oversized cast bullets intended for maximum friction fit. The die has handled all of them with aplomb, consistently providing a secure crimp that holds up even when subjected to simulated heavy recoil conditions. There are no signs of wear on the die itself, and it continues to function as smoothly as it did on day one. This level of durability is exactly what I expect from reliable reloading components.
Breaking Down the Features of LEE 90813 COLLECT CRIMP DIE 357 MAG
The core appeal of the LEE 90813 COLLECT CRIMP DIE 357 MAG lies in its specialized function and robust construction. This die is designed to provide a powerful and secure crimp, particularly beneficial for heavy recoiling cartridges like the .357 Magnum, or when using oversized bullets that might otherwise seat too deeply. It’s a tool built for a specific purpose, and it excels at that purpose due to its unique design.
The specifications provided highlight its dedication to the .357 Magnum caliber and handgun use. The Lee manufacturer is known for producing practical, effective reloading tools, and this die is a prime example. Its focus is not on broad applicability but on delivering a superior crimp for its intended applications. The die’s caliber is precisely .357 Magnum, ensuring optimal performance for that cartridge. Its gun type classification as Handgun further refines its intended use, making it a targeted solution for revolver and pistol reloaders.
Specifications
The LEE 90813 COLLECT CRIMP DIE 357 MAG is a specialized tool designed for a singular, critical function in the reloading process. Its primary specification is its caliber: .357 Magnum. This means it is precisely engineered to work with the dimensions of .357 Magnum cartridges and cases.
This focus on a specific caliber is crucial for effective crimping. The die’s gun type is listed as Handgun, reinforcing its suitability for revolvers and other handguns chambered in .357 Magnum. The manufacturer, Lee, is a well-respected name in the reloading industry, known for providing functional and affordable tools.
The unique selling proposition of this die is its collect crimp system. Unlike standard taper or roll crimps, this mechanism is designed to apply a more aggressive crimp, effectively gripping the bullet within the case mouth. This is particularly useful when reloading cast bullet ammunition, where some bullets may lack a pronounced crimp groove. The die’s design is powerful enough that it can actually form a crimp groove if one is absent. This feature alone makes it invaluable for reloaders who frequently work with cast projectiles or desire an exceptionally secure bullet seating for heavy recoiling firearms.
Performance & Functionality
In terms of its primary function, the LEE 90813 COLLECT CRIMP DIE 357 MAG performs exceptionally well. Its main job is to provide a secure crimp, and it delivers on this promise with significant authority. I’ve found that it secures bullets far more effectively than standard crimping dies, especially when dealing with the nuances of cast bullets.
The strength of this crimp is a significant advantage. It minimizes or entirely eliminates bullet creep, a common issue with heavy recoiling cartridges like the .357 Magnum. Even with bullets that don’t possess a deep, dedicated crimp groove, this die manages to create a tenacious hold. This level of performance exceeds my expectations for a die in this price range.
Design & Ergonomics
The design of the LEE 90813 COLLECT CRIMP DIE 357 MAG is purely functional, aligning with Lee‘s reputation for practical tooling. The die’s construction feels robust, made from what appears to be hardened steel, which is essential for a tool that exerts significant force on cartridge cases. It fits standard reloading press die stations without any issues.
Ergonomically, as with most reloading dies, its use is integrated into the press operation. The adjustment mechanism, typically a knurled ring, allows for fine-tuning of the crimp pressure. It’s comfortable enough to operate during a reloading session, and the tactile feedback from the adjustment ring is clear. There isn’t a significant learning curve; the effectiveness comes from understanding how much crimp is needed for your specific load and bullet combination.
Durability & Maintenance
The durability of the LEE 90813 COLLECT CRIMP DIE 357 MAG is impressive for its straightforward design. Given its all-metal construction and the fact that it’s designed for repetitive mechanical action, it feels built to last. I haven’t encountered any issues with wear or deformation, even after processing a considerable number of rounds.
Maintenance is minimal. After a reloading session, a simple wipe-down with a soft cloth and a light application of lubricant on the threads is sufficient. It’s important to keep the die clean and free from powder residue or debris that could interfere with its function or damage cases. I also make sure to store it properly, typically back in its original packaging or in a die rack, to protect the threads and internal components. There are no apparent failure points; its robust build suggests it should provide many years of reliable service.
Accessories and Customization Options
The LEE 90813 COLLECT CRIMP DIE 357 MAG typically functions as a standalone component within a reloading setup. It is designed to be used as part of a full resizing and de-priming die set, or as a dedicated crimping die after bullet seating. No specific accessories are typically bundled with the die itself, as its function is self-contained within the reloading press.
However, its compatibility with standard reloading presses is a key feature. It utilizes the standard 7/8″-14 thread pattern common to most reloading presses, meaning it will integrate seamlessly with presses from Lee, Dillon, RCBS, Hornady, and others. This standardization means you don’t need specialized equipment to use this die; it’s a direct replacement or addition to your existing setup. While there aren’t “customization options” for the die itself, its effectiveness can be customized through the careful adjustment of its crimp pressure, allowing reloaders to tailor the tightness of the crimp to their specific needs.
