RCBS M500 Mechanical Scales Review

Let’s Dive into RCBS M500 Mechanical Scales

The RCBS M500 Mechanical Scales represent a cornerstone in the world of reloading, offering a blend of precision, reliability, and straightforward operation. Manufactured by RCBS, a name synonymous with quality reloading equipment, these scales promise accuracy down to +/-0.1 grain. This makes them an essential tool for anyone serious about crafting consistent and safe ammunition.

My journey to acquiring the RCBS M500 Mechanical Scales started with a growing frustration with the inconsistency of my powder throws using a volumetric dispenser. While convenient, it lacked the precision I desired for my match-grade rifle loads. I needed a reliable method to verify and, if necessary, adjust each charge to ensure optimal performance and safety.

Unboxing the RCBS M500 Mechanical Scales revealed a solid, well-built piece of equipment. The die-cast aluminum base felt substantial, lending a sense of stability. The metal pan appeared durable. The scales had a reassuring heft.

I considered several alternatives, including digital scales and other mechanical models from competing brands like Hornady and Lyman. I chose the RCBS M500 Mechanical Scales primarily for their reputation for accuracy and their ambidextrous design. Also, the absence of batteries was a significant draw. I value simplicity and reliability over the bells and whistles of electronic devices.

My first impression was one of quiet confidence. The RCBS M500 Mechanical Scales exuded a sense of no-nonsense functionality. I anticipated a learning curve, but also trusted in the proven design to deliver the accuracy I needed.

Real-World Testing: Putting RCBS M500 Mechanical Scales to the Test

First Use Experience

I first tested the RCBS M500 Mechanical Scales in my reloading room, a controlled environment shielded from drafts and vibrations. I used them to measure charges for .308 Winchester rounds intended for long-range target shooting. The scales proved easy to set up.

Performance remained consistent throughout the initial testing session. Despite carefully monitoring for environmental factors, variations did not impact readings. The RCBS M500 Mechanical Scales felt intuitive, even for a first-time user of mechanical scales.

The only minor hiccup was my initial unfamiliarity with reading the vernier scale. It required a few practice runs to confidently interpret the precise grain measurements. After a short adjustment period, the process became seamless.

Extended Use & Reliability

After several months of consistent use, the RCBS M500 Mechanical Scales have proven to be a reliable and accurate tool. They have become an indispensable part of my reloading process.

Durability has been excellent. The scales show no signs of wear and tear despite regular use. The die-cast aluminum base resists scratches and the pivots maintain smooth movement.

Maintenance is minimal. I occasionally dust the scales and check the zero. I have never needed to recalibrate them. Compared to my previous experiences with less precise powder measuring methods, the RCBS M500 Mechanical Scales have significantly improved the consistency and accuracy of my reloads.

Breaking Down the Features of RCBS M500 Mechanical Scales
