How I Used the Lee Taper Crimp Die For 9MM/38 Super/380 ACP/38 ACP 90780 and What I Found
For reloaders facing the persistent annoyance of unreliable case feeding, the Lee Taper Crimp Die For 9MM/38 Super/380 ACP/38 ACP 90780 presents itself as a potential salvation. Manufactured by Lee, a name synonymous with accessible and effective reloading components, this die promises to rectify issues stemming from improper case crimping. Its hardened steel construction and specific taper crimp design aim to eliminate the “shouldering” effect that plagues many semi-automatic pistol rounds, particularly in calibers like 9mm, .38 Super, .380 ACP, and .38 ACP.
My journey to this particular die was born out of sheer frustration. I had been experiencing an unacceptable rate of jams in both my .380 ACP and 9mm handloads. Initially, I suspected incorrect overall cartridge length, a common culprit. However, after meticulously adjusting the seating depth with various lengths, the problem persisted, leading to frustrating malfunctions on the range. The core issue, I discovered, lay within the limitations of standard three-die pistol sets. They struggled to achieve a proper bullet seat depth without simultaneously deforming the case mouth or, conversely, leaving a distinct shoulder that choked magazine feeding.
The allure of the Lee Taper Crimp Die was its dedicated purpose: to isolate the crimping step and apply it precisely. I had considered other brands, but the reputation of Lee Precision for value and practical innovation in reloading tools made this die a compelling choice, especially given its modest price point. My initial impressions upon receiving the die were positive. It felt substantial, a solid piece of hardened steel that exuded durability. The threading was clean, and it mounted smoothly into my reloading press. There was a quiet confidence that emanated from its simple, robust design; it looked like it was built to last, ready to tackle the demands of consistent reloading.
Real-World Testing: Putting Lee Taper Crimp Die For 9MM/38 Super/380 ACP/38 ACP 90780 to the Test
My initial use of the Lee Taper Crimp Die For 9MM/38 Super/380 ACP/38 ACP 90780 took place at my home reloading bench, paired with an RCBS Rock Chucker press. The process was straightforward: after seating the bullet to the desired depth with my seating die, I ran the cartridge through the taper crimp die in the fourth station of my press. Following the enclosed instructions was key; a slight adjustment of the die body allowed me to achieve the perfect taper crimp.
The immediate result was a tangible improvement. The case mouth no longer presented a snagging point, and the cartridges fed into the chamber with a noticeable smoothness. This die performed precisely as advertised, creating a cleaner transition to the bullet and effectively eliminating the shoulder that had been causing all my prior feeding issues. I tested this on numerous batches of .380 ACP and 9mm ammunition, and the results were consistent across the board.
Over several months of regular reloading, this die has proven itself to be remarkably reliable. It’s become an indispensable part of my reloading process for semi-automatic pistol cartridges. I’ve experienced no degradation in its performance, even after processing hundreds of rounds. The hardened steel construction shows no signs of premature wear, nor has it developed any stiffness or deformation. Maintenance is minimal; a simple wipe down with a dry cloth after use and occasional light oiling is all that’s needed to keep it in top condition. Storing it with my other dies in a standard die box has been perfectly adequate. Compared to the frustration I experienced with less specialized dies, this dedicated taper crimp die offers a significantly more consistent and reliable outcome.
Breaking Down the Features of Lee Taper Crimp Die For 9MM/38 Super/380 ACP/38 ACP 90780
Specifications
The Lee Taper Crimp Die For 9MM/38 Super/380 ACP/38 ACP 90780 is meticulously crafted from hardened steel, a critical material choice that ensures longevity and resistance to wear. It is designed to work with multiple pistol calibers, specifically supporting .38 ACP, 9mm Luger, .380 ACP, and .38 Super. This multi-caliber capability, coupled with its taper crimp pistol die functionality, makes it a versatile addition to many reloaders’ toolkits.
The die’s heavy-duty construction and metal housing are engineered for a lifetime of use, a promise that aligns with Lee Precision’s reputation for producing robust reloading components. The hardened steel construction is paramount for maintaining its precise crimping dimensions over countless cycles, preventing the gradual rounding or deformation that can occur with lesser materials. This attention to material quality directly translates into more consistent ammunition and fewer feeding malfunctions.
Performance & Functionality
The primary function of this taper crimp die is to remove the case mouth “shoulder” and apply a gentle, tapered crimp to the case mouth, ensuring smooth feeding in semi-automatic firearms. It excels at this task, delivering consistently reliable results that significantly reduce feeding issues. The die’s ability to create a clean, smooth transition from the case mouth to the bullet is its standout performance characteristic.
Its main strength lies in its dedicated design; it’s not trying to be a seater and a crimper in one, but rather to perfect the crimp. This specialization allows it to outperform the crimping capability of many standard three-die sets. A minor weakness, if one could call it that, is its reliance on the user having correctly adjusted seating depth beforehand. However, this is more a testament to proper reloading technique than a flaw of the die itself. For its intended purpose, it exceeds expectations, especially when tackling cartridges known for their feeding sensitivities.
Design & Ergonomics
The design of the Lee Taper Crimp Die is elegantly simple and functional. It features standard reloading die threading, allowing for easy installation into any compatible press. The exterior is finished with a durable coating that offers a good grip, even with slightly greasy hands.
The die body is sized appropriately to fit comfortably in hand for adjustments. The markings on the die are clear and legible, aiding in precise setting. Its ergonomic design focuses on straightforward application; once set, it requires no complex manipulation during the reloading process. This no-fuss approach is a hallmark of Lee Precision tools.
Durability & Maintenance
Given its hardened steel construction, the Lee Taper Crimp Die is built for exceptional durability. Under normal reloading conditions, it is designed to last for decades, if not a lifetime. I have experienced no issues with wear or performance degradation in my extended testing.
Maintenance is refreshingly straightforward. A simple wipe-down after use with a soft cloth, and perhaps a light application of gun oil or universal firearm lubricant on the threads and internal workings, is sufficient. It’s important to keep it clean and dry to prevent rust or corrosion, though the robust construction offers good resistance. There are no specific failure points to note; its solid metal construction minimizes the risk of breakage.
Accessories and Customization Options
As a single die, the Lee Taper Crimp Die For 9MM/38 Super/380 ACP/380 ACP 90780 does not come with additional accessories. Its primary function is integrated into the reloading process. However, its standard threading means it can be used in conjunction with nearly any brand of reloading press and other dies, provided they adhere to industry standards.
There are no direct customization options for the die itself. Its purpose is singular and well-defined. The value comes from its specialized function rather than modularity. For best results, it is recommended to use it in a progressive press with a fourth station, or to dedicate a single-stage press to the task if necessary, to ensure optimal control over the crimp.
