Let’s Talk About Lyman 7690107 MSR Precision Die System 4-Die Set 9mm Luger

Reloading for an MSR platform, especially in 9mm, presents unique challenges. The tolerances are tighter, the demands for consistent performance are higher, and the potential for malfunctions due to inconsistent ammunition is a real concern. Lyman, a trusted name in reloading, steps up to the plate with the Lyman 7690107 MSR Precision Die System 4-Die Set 9mm Luger, promising to deliver the precision and reliability required for optimal MSR performance. This set aims to ensure smooth chambering, tight bullet grip, and overall ammunition consistency, features that immediately piqued my interest.

For years, I’ve been using a mixed bag of standard reloading dies, jury-rigging solutions to get acceptable results. I was looking for a dedicated solution designed specifically to address the tighter tolerances and higher performance demands of MSR-platform 9mm ammunition. My goal was improved reliability and accuracy, something my current setup wasn’t consistently delivering.

Upon unboxing, the first thing that struck me was the solid, professional feel of the Lyman dies. The black finish is attractive and seems durable, and the clear storage case is a welcome touch for keeping everything organized. Each die feels substantial, exhibiting the quality I expect from Lyman.

I considered the Redding 9mm die set and the Dillon Precision 9mm dies. Ultimately, I chose the Lyman 7690107 MSR Precision Die System 4-Die Set 9mm Luger because it specifically addresses the needs of MSR platforms. I also appreciated the inclusion of the Ammo Checker cartridge die, which seemed like a valuable tool for ensuring consistent ammunition dimensions.

My initial reaction was one of cautious optimism. I was excited to try out the Ammo Checker and the Small Base die, hoping they would deliver on their promises of improved reliability. However, I was also slightly concerned about the learning curve associated with a new die set, particularly one designed for such a specific application.
