Let’s Talk About Lee Undersize Sizing Die Only Carbide 9mm Luger
The Lee Undersize Sizing Die Only Carbide 9mm Luger is a reloading die designed to resize 9mm Luger cartridge cases. Lee Precision is a well-known manufacturer in the reloading world, famous for providing affordable and reliable equipment. This particular die aims to ensure consistent and accurate case sizing, which is crucial for reliable feeding and proper chambering in 9mm pistols.
I was having issues with some of my reloads not chambering reliably in a tight-tolerance 9mm pistol. I suspected that my existing sizing die wasn’t quite getting the cases down to the correct dimensions, especially after multiple reloads. The promise of an undersized die, offering a tighter fit, seemed like the perfect solution.
Upon receiving the die, I immediately noticed its solid construction. The carbide insert looked well-polished and properly seated within the steel body. The die had a good weight to it, suggesting durable materials, ready to withstand the repetitive forces of resizing. I was eager to see how it performed.
I considered the RCBS Small Base Sizing Die and the Dillon Carbide Sizing Die before ultimately choosing the Lee. I went with the Lee die due to its reputation for producing consistent results and the significantly lower price point. My initial impression was positive; it seemed like a well-made tool that could potentially solve my chambering issues at a reasonable cost.
Real-World Testing: Putting Lee Undersize Sizing Die Only Carbide 9mm Luger to the Test
First Use Experience
My first experience with the Lee Undersize Sizing Die was at my reloading bench in my garage. I processed a batch of mixed headstamp 9mm brass, some of which had been reloaded multiple times. I immediately noticed the effort required to resize the cases was slightly higher than with my standard sizing die.
The resized cases looked noticeably more uniform. They chambered much more smoothly in my problematic pistol. The Lee die seemed to be doing its job of bringing the cases back to spec.
Extended Use & Reliability
After several hundred rounds reloaded with the Lee Undersize Sizing Die, I’ve been consistently impressed with its performance. It has shown no signs of wear and tear, and the carbide insert remains smooth. The external finish has held up well.
Maintenance is simple; a quick wipe down with a clean cloth keeps it in good condition. Compared to my previous sizing die, the Lee die provides a much more consistent and reliable sizing experience, greatly reducing chambering issues. The reloaded rounds feed reliably, resulting in improved accuracy at the range.
