RCBS Chamber/Case Length Gauge Review

Let’s Talk About RCBS Chamber/Case Length Gauge

The RCBS Chamber/Case Length Gauge isn’t the sexiest piece of reloading equipment on the market, but it is a critical tool for ensuring safe and reliable ammunition. Made by RCBS, a trusted name in reloading, this gauge offers a simple and effective way to verify that your pistol cartridges are within the correct dimensions before you head to the range. It promises peace of mind, a commodity valued above all else when handling firearms.

I decided to get one of these gauges after experiencing a few failures to chamber with some of my reloads. I was chasing consistency and accuracy, and a nagging doubt about case length was undermining my confidence. I’d heard too many stories of over- or under-length cartridges causing feeding issues, or even worse, pressure problems.

The RCBS Chamber/Case Length Gauge arrived in a simple, no-frills package. The gauge itself is a solid, one-piece block of steel, with clearly engraved caliber markings. It feels substantial and well-made, definitely built to last.

Compared to using a caliper, which requires multiple measurements and careful attention to tolerances, this gauge offers a go/no-go solution that’s much faster. Some reloaders swear by dial calipers and case trimmers alone, but I wanted the extra security this offered. My initial impression was positive: it’s a simple tool that appears well-executed and should quickly identify out-of-spec ammunition. I was excited to see how much it streamlined my reloading process.

Real-World Testing: Putting RCBS Chamber/Case Length Gauge to the Test

First Use Experience

My first test with the RCBS Chamber/Case Length Gauge was at my reloading bench, after processing a batch of 9mm Luger brass. I had just resized, deprimed, and trimmed the cases, and wanted to check their final dimensions before priming and loading. The process was incredibly simple: drop each case into the gauge, and if it fits flush, it’s good to go.

I tested the gauge with cases that I knew were at the high end of the acceptable length range, as well as some deliberately trimmed a bit short. The gauge clearly differentiated between the two, rejecting the oversized cases. There were no failures to feed during the subsequent range testing of ammunition that passed. The RCBS Chamber/Case Length Gauge worked as advertised.

Extended Use & Reliability

After several months of using the RCBS Chamber/Case Length Gauge, I’ve come to appreciate its reliability and consistency. It has become a standard part of my reloading workflow, used after every resizing and trimming session. I am confident that the gauge is accurately identifying out-of-spec ammunition.

The gauge shows no signs of wear and tear, despite frequent use. Cleaning is simple; a quick wipe with a cloth is usually all it needs. Compared to spending time measuring each case, the RCBS Chamber/Case Length Gauge saves a significant amount of time without sacrificing quality control. It significantly outperforms the “eyeball” method, and gives me more confidence than relying on resizing alone.

Breaking Down the Features of RCBS Chamber/Case Length Gauge

Specifications

The RCBS Chamber/Case Length Gauge is a precisely machined tool designed to check critical dimensions of pistol ammunition. Key specifications include:

• One-piece, non-adjustable design: This simplicity ensures accuracy and eliminates the potential for user error.
• Checks chambering and cartridge length: Ensures proper fit in the firearm’s chamber, as well as correct overall cartridge length.
• Easy-to-read engravings display caliber size: Quickly identifies the correct gauge for the cartridge being loaded.
• Material: Machined steel. Offers excellent durability and resistance to wear.

These specifications are critical because they directly impact the safety and reliability of the ammunition. Cartridges that are too long may not chamber properly, leading to failures to feed or, in extreme cases, dangerous pressure spikes.

Performance & Functionality

The RCBS Chamber/Case Length Gauge performs its job exceptionally well. It provides a quick and easy way to confirm that ammunition is within SAAMI specifications, ensuring proper chambering and safe firing. The gauge’s strength lies in its simplicity and speed.

The main strength is its ease of use. The weakness is that it only indicates whether a cartridge is within spec or not; it doesn’t provide precise measurements like a caliper. This tool meets my expectations perfectly.

Design & Ergonomics

The RCBS Chamber/Case Length Gauge features a simple and functional design. It’s a solid block of steel, sized appropriately for the caliber it’s designed to check. The engravings are clear and easy to read.

It is a very user-friendly tool. There is virtually no learning curve.

Durability & Maintenance

The RCBS Chamber/Case Length Gauge is built to last. The steel construction ensures it can withstand years of use without significant wear or damage. It should last a lifetime with proper care.

Maintenance is minimal; a quick wipe with a clean cloth after each use is sufficient to keep it in good condition. No repair is required.

Accessories and Customization Options

The RCBS Chamber/Case Length Gauge is a standalone tool and doesn’t require any accessories. There are no customization options available. The value lies in its precise design, which is optimized for a specific set of dimensions. While not technically an accessory, a case trimmer is a must-have tool to use in conjunction with the gauge.

Pros and Cons of RCBS Chamber/Case Length Gauge

Who Should Buy RCBS Chamber/Case Length Gauge?

The RCBS Chamber/Case Length Gauge is perfect for reloaders of all skill levels who want to ensure the safety and reliability of their ammunition. It’s especially valuable for:

• Pistol reloaders: Ensures reliable feeding in semi-automatic pistols.
• High-volume reloaders: Speeds up the quality control process.
• Those seeking consistency: Helps maintain uniform cartridge dimensions for improved accuracy.

Someone who primarily shoots factory ammunition and doesn’t reload would not need this product. A must-have accessory is a quality case trimmer if one doesn’t exist already.

Conclusion on RCBS Chamber/Case Length Gauge

The RCBS Chamber/Case Length Gauge is a simple but essential tool for any pistol reloader. It offers a fast and reliable way to verify that ammunition is within SAAMI specifications, promoting both safety and consistent performance. The affordability and durability make it a worthwhile investment.

The price is absolutely justified given the peace of mind and time savings it provides. I would highly recommend the RCBS Chamber/Case Length Gauge to anyone who reloads pistol ammunition. Take the guesswork out of your reloading process and shoot with confidence!
