Let’s Dive into Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720
The Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 promises tighter groups and extended case life, a siren song to any serious reloader. Designed to neck size only, this die set from Lee aims to improve accuracy by minimizing run-out and work hardening of the brass. It’s a unique approach compared to full-length sizing, and I was eager to see if it lived up to the hype.
Years of chasing the perfect load for my 7mm Rem Mag hunting rifle led me down the reloading rabbit hole. I was tired of inconsistent neck tension and cases that seemed to wear out after just a few firings, even with careful annealing. The promise of increased case life and improved bullet seating concentricity piqued my interest in the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720.
My first impression upon unboxing was that the dies looked… well, like Lee dies. Functional, but not exactly polished. The included shellholder was a welcome addition, though. Compared to my RCBS full-length die set for the same caliber, the Lee die felt lighter and simpler in design. I picked the Lee set to try something different in my reloading process.
My initial reaction was cautiously optimistic. The design was intriguing, and the price was certainly right, but I was a little concerned about the “rough around the edges” feel. I was hoping the performance would outweigh the lack of aesthetic appeal. The potential for accuracy gains was the ultimate goal.
Real-World Testing: Putting Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 to the Test
First Use Experience
I tested the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 in my reloading room, which is usually a controlled environment, but this time I decided to test the set after coming home from the range where some rounds got a little dirty from the dusty conditions. I wanted to see how well the sizing process worked after the brass had picked up range grit. The Lee die required a bit more force than my full-length sizer.
I found the die set easy to use, but it definitely required a different touch than full-length sizing. The instructions were clear, but I did need to watch a few videos online to fully understand the nuances of collet neck sizing. After sizing the brass I primed and loaded 50 rounds for a follow up range test.
After my initial use, I noticed the rounds I loaded using the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 fed smoothly. I was also glad that even though there was range dust on some of the brass before sizing, I did not see any marring or scratching on the case necks of the newly loaded rounds.
Extended Use & Reliability
After several months of use, the Lee Collet Die Set W/Shellholder For 7MM Remington Mag 90720 continues to perform well. I’ve reloaded several batches of 7mm Rem Mag brass, and I’m seeing no signs of premature wear. My cases are holding up nicely to continued reloading.
The dies themselves show no signs of wear, despite regular use. Cleaning is simple, requiring only a quick wipe down with a clean cloth and a light coat of oil. Compared to my experience with full-length sizing, I believe the collet die is gentler on the brass, resulting in less work hardening. I feel confident that it will continue to do so over time.
