Lee Collet Die Set W/Shellholder For 7X57 Mauser 90714 Review

Let’s Dive into Lee Collet Die Set W/Shellholder For 7X57 Mauser 90714

The Lee Collet Die Set W/Shellholder For 7X57 Mauser 90714 promises precision reloading, focusing on neck sizing to extend case life and enhance accuracy. This die set, manufactured by Lee, utilizes a collet system to squeeze the case neck against a mandrel, ensuring proper alignment and minimizing run-out. It’s a different approach to reloading compared to full-length sizing, and that difference piqued my interest.

I was looking for a way to improve the consistency of my 7×57 Mauser loads. I had a rifle that showed great potential, but I suspected my reloading process might be holding it back. I also wanted to extend the life of my brass, as finding good 7×57 brass can be a challenge.

Upon opening the box, I was immediately struck by the simplicity of the Lee collet die design. The weight felt solid and the components seemed well-machined, exhibiting Lee’s typical robust build quality despite the reasonable price. The kit included the collet die, a mandrel, and the Lee shellholder, everything needed to start neck sizing 7×57 Mauser cases.

I considered the RCBS neck sizing die and the Redding Competition neck sizing die before settling on the Lee. The RCBS is a solid performer, but I was intrigued by the Lee’s collet design, which is known to reduce case runout. The Redding is a premium option, but the Lee offered a similar concept at a fraction of the price, making it a worthwhile experiment.

My first impression was one of cautious optimism. The design was unconventional compared to traditional sizing dies, but the promise of increased accuracy and extended case life was too good to ignore. I was eager to see if the Lee Collet Die Set W/Shellholder For 7X57 Mauser 90714 could live up to the hype.


Real-World Testing: Putting Lee Collet Die Set W/Shellholder For 7X57 Mauser 90714 to the Test

First Use Experience

I tested the Lee Collet Die Set W/Shellholder For 7X57 Mauser 90714 at my reloading bench, preparing ammunition for an upcoming deer hunt. The controlled environment of my reloading room allowed for precise measurements and careful observation of the die’s performance.

The die performed consistently, even after prolonged use. Cases sized smoothly, and the mandrel ensured consistent neck tension. The setup was simple and quick. I did not have to adjust the die much after the initial setup.

There were no major issues during the initial use, but I noticed that the collet occasionally left a slight ring on the case neck. I later learned that this is normal and doesn’t affect performance. I was also surprised by how little effort was required to size the case necks compared to full-length sizing.

Compared to my previous full-length sizing die, the Lee Collet Die Set has significantly improved case life. I’ve noticed fewer case neck splits and a more consistent feel when seating bullets. Overall, this die set has exceeded my expectations in terms of both performance and longevity.
