Let’s Dive into LEE 90725 FACT CRIMP DIE 5.7X28 FN
The LEE 90725 FACT CRIMP DIE 5.7X28 FN is a specialized reloading die designed to improve the consistency and accuracy of ammunition for firearms chambered in 5.7x28mm. Manufactured by Lee, this die aims to provide a uniform crimp, enhancing bullet seating and overall performance. For reloaders seeking to optimize their 5.7x28mm rounds, this tool promises a noticeable difference in accuracy and velocity consistency.
My interest in the LEE 90725 FACT CRIMP DIE 5.7X28 FN stemmed from a personal quest for tighter groupings with my FN Five-seveN. I was experiencing some inconsistent velocities and group sizes that I suspected were related to bullet seating depth and crimp inconsistencies. I wanted to find a way to achieve a more uniform and reliable crimp on my 5.7x28mm reloads.
Upon unboxing, the LEE 90725 FACT CRIMP DIE 5.7X28 FN appeared robust and well-machined. The die felt solid in hand, and the threads were clean and precise. The included instructions were clear and concise, a pleasant surprise compared to some reloading tools I’ve encountered in the past.
I considered other crimping options, including a traditional roll crimp die and a collet-style crimp die from another manufacturer. Ultimately, I chose the LEE Factory Crimp Die because of its reputation for ease of use and its ability to crimp bullets even without a dedicated crimp groove. The price point was also a significant factor, offering a good balance between cost and performance.
My first impression was optimistic. The die seemed well-made and straightforward to use. I was eager to see if it could deliver on its promise of improved accuracy and consistency in my 5.7x28mm reloads.
Real-World Testing: Putting LEE 90725 FACT CRIMP DIE 5.7X28 FN to the Test
First Use Experience
My initial testing took place at my local shooting range, where I have access to a chronograph and various target distances. I loaded a batch of 5.7x28mm rounds with and without the LEE 90725 FACT CRIMP DIE 5.7X28 FN, using the same powder charge, bullet type, and seating depth. The weather was dry and mild, providing optimal conditions for testing.
The LEE Factory Crimp Die proved to be incredibly easy to use. After setting the die up in my reloading press according to the instructions, crimping each round was a breeze. I immediately noticed a more consistent feel during the crimping process compared to my previous method.
There were no immediate issues after the first use. The die functioned smoothly, and the resulting crimps appeared uniform and well-defined. I was anxious to see how these rounds would perform downrange.
Extended Use & Reliability
After several weeks of reloading and shooting with the LEE 90725 FACT CRIMP DIE 5.7X28 FN, I can confidently say it has held up exceptionally well. The die shows no signs of wear and tear, despite crimping hundreds of rounds. It still operates smoothly and consistently.
The LEE die is very easy to maintain. A quick wipe down with a clean cloth after each reloading session is usually sufficient. I also apply a light coat of gun oil to the threads occasionally to prevent corrosion and ensure smooth operation.
Compared to my previous reloading experience, the LEE 90725 FACT CRIMP DIE 5.7X28 FN has significantly improved the consistency and accuracy of my 5.7x28mm reloads. My group sizes have shrunk noticeably, and my chronograph readings show a tighter velocity spread. It has definitely exceeded my expectations.
Breaking Down the Features of LEE 90725 FACT CRIMP DIE 5.7X28 FN
Specifications
The LEE 90725 FACT CRIMP DIE 5.7X28 FN is specifically designed for crimping 5.7x28mm ammunition. It is a carbide factory crimp die, meaning it doesn’t require lubrication for most cases, adding to its ease of use. Its primary function is to firmly crimp the bullet in place, regardless of whether the bullet has a crimp groove.
The die’s ability to improve accuracy, even with bullets lacking a traditional crimp groove, is what sets it apart. A firm crimp enhances accuracy by ensuring that pressure builds to a higher, more consistent level before the bullet begins to move. This leads to a more uniform pressure curve and reduced velocity variation.
Performance & Functionality
The LEE 90725 FACT CRIMP DIE 5.7X28 FN performs its job admirably. Its primary strength lies in its ability to create a consistent and uniform crimp, which directly translates to improved accuracy and velocity consistency. It’s also easy to use, even for novice reloaders.
While the die excels at crimping, it’s essential to ensure the bullet seating depth is correct before crimping. The die will not correct for improperly seated bullets. Meeting expectations is an understatement; it has significantly improved the performance of my 5.7x28mm reloads.

Maintaining the die is simple. A quick wipe down with a clean cloth and a light coat of gun oil are all that’s needed. The die’s robust construction and simple design make it easy to maintain and repair, if ever necessary.
Accessories and Customization Options
The LEE 90725 FACT CRIMP DIE 5.7X28 FN doesn’t come with any specific accessories, as it’s a standalone die. However, it is compatible with most standard reloading presses that accept 7/8″-14 threaded dies.

The die works perfectly with Lee‘s breech lock quick change bushings to speed up the reloading workflow.
