First Impressions of Evolution Gun Works Case Gauge Ammo Checker 9 mm Major 50-Hole
Reloading ammunition for competitive shooting, especially in disciplines like USPSA where “Major” power factor is the name of the game, demands precision. Minor variations in case dimensions can mean the difference between a stage win and a frustrating malfunction, or worse, a dangerous overpressure situation. That’s why, after years of manually checking my 9mm Major reloads, I decided to invest in a dedicated case gauge – the Evolution Gun Works Case Gauge Ammo Checker 9 mm Major 50-Hole.
For years I’d relied on plunk tests in my match pistol and a Wilson Combat single-round gauge. While functional, it was incredibly time consuming to check the hundreds of rounds needed for a weekend match. The Evolution Gun Works gauge promised a faster, more consistent method, allowing me to quickly identify and cull any rounds that fell outside of acceptable tolerances.
The gauge arrived in simple, no-frills packaging. My initial impression was positive. It had a solid feel and the matte black finish looked professional. Compared to the plastic gauges I’d seen, this felt like a serious piece of equipment. Other gauges I considered were from brands like Lyman and Dillon Precision, but the Evolution Gun Works gauge stood out due to its reputation for precision and the specific “9mm Major” chambering, tailored to my competition needs. I hoped it would live up to its promise of improving my reloading efficiency and ensuring reliability on the range.
Real-World Testing: Putting Evolution Gun Works Case Gauge Ammo Checker 9 mm Major 50-Hole to the Test
First Use Experience
My initial test of the Evolution Gun Works Case Gauge Ammo Checker 9 mm Major 50-Hole took place in my reloading room. I was preparing ammunition for an upcoming USPSA match in a dry climate with temperatures hovering around 75 degrees Fahrenheit. The first few uses revealed how simple the gauge was to operate. Dropping rounds into the 50 holes was quick and easy.
Rounds that fit perfectly dropped flush with the top surface. Cases that were slightly bulged, or had improperly seated bullets protruded noticeably, making them easy to identify and remove. I did experience a few instances where rounds seemed to stick slightly, requiring a gentle tap to fully seat, but this was infrequent. After the first session, I noticed how much faster I was than using the single-round gauge.
Extended Use & Reliability
After several months of use, the Evolution Gun Works Case Gauge Ammo Checker 9 mm Major 50-Hole has become an indispensable part of my reloading process. I typically check between 300-500 rounds per session. The gauge has shown no signs of wear and tear. The aluminum construction is holding up well. Cleaning is simple, requiring only a quick wipe down with a microfiber cloth to remove any powder residue or debris.
Compared to my previous method of manually checking each round, the Evolution Gun Works gauge has drastically reduced the time it takes to prepare match ammunition. It also provides a much higher level of consistency. I’ve noticed a significant decrease in malfunctions during matches, directly attributable to the improved quality control afforded by the gauge.

Performance & Functionality
The Evolution Gun Works Case Gauge Ammo Checker 9 mm Major 50-Hole performs its primary function exceptionally well. It accurately identifies rounds that are out of spec, preventing potential malfunctions and ensuring consistent performance. The gauge’s strengths lie in its speed and ease of use.
However, it’s worth noting that the gauge does not identify why a round is out of spec, only that it is. Determining the cause (e.g., bulged case, improperly seated bullet) requires further inspection. Ultimately, the gauge meets and exceeds my expectations for a rapid, reliable ammunition checker.
Design & Ergonomics
The gauge is constructed from a single piece of aluminum. This gives it a solid, robust feel. The weight is light enough to easily manipulate, but heavy enough to stay in place on the reloading bench.
The design is simple and intuitive, with no moving parts. The matte black finish provides a non-slip surface and reduces glare. There’s virtually no learning curve. Anyone familiar with reloading can immediately start using the gauge effectively.
Durability & Maintenance
The 6061-T6 aluminum construction ensures excellent durability. After months of use, there are no signs of wear, scratches, or deformation. The gauge should last for many years with proper care. Maintenance is minimal, consisting of occasional cleaning to remove powder residue and dirt.
Accessories and Customization Options
