Real-World Testing: Putting RCBS Quick Change Metering Screw Assembly to the Test

First Use Experience

My initial testing of the RCBS Quick Change Metering Screw Assembly took place on my dedicated reloading bench. This is where I spend a considerable amount of time, meticulously weighing and dispensing powder for various rifle and pistol cartridges. The environment is controlled, but it demands accuracy and consistency above all else. The process of replacing the old metering screw with the new one was straightforward, fitting perfectly into my existing RCBS Uniflow powder measure.

Performance was immediately noticeable. Switching between a fine-grained powder for .223 loads and a coarser propellant for .30-06 loads became a significantly faster operation. The quick change mechanism, once understood, allowed for a swap in mere moments, minimizing downtime between different reloading tasks. There were no immediate issues or surprising quirks; the fit and function were as expected from a reputable manufacturer like RCBS.

Extended Use & Reliability

After several weeks of consistent use, encompassing dozens of powder dispensing cycles for various calibers, the metering screw assembly has held up exceptionally well. Its performance hasn’t degraded, and the precision of the dispensed charges remains remarkably consistent. The hardened steel construction shows no discernible signs of wear, such as scratches, scuffs, or any stiffness developing in its operation.

Maintenance and care for this component are minimal, which is a significant advantage. A quick wipe-down with a dry cloth after use is usually sufficient to keep it clean and functioning optimally. Compared to the original screw, the ease of swapping and the reliability it offers are a clear step up. It performs consistently, whether dispensing tiny charges of fast-burning pistol powder or larger volumes of slow-burning rifle propellant.

Breaking Down the Features of RCBS Quick Change Metering Screw Assembly

Specifications

The RCBS Quick Change Metering Screw Assembly is a single unit designed to replace the standard metering screw in an RCBS Uniflow powder measure. Constructed from hardened steel, this assembly is built for longevity and resistance to wear, crucial for maintaining accurate powder dispensing over time. Its primary function is to facilitate faster changes between different powder dispensing volumes.

This specification is vital because it directly impacts reloading speed and convenience. Being able to switch accurately and quickly between settings for different cartridges saves valuable time and reduces the likelihood of errors that can occur when fumbling with less user-friendly mechanisms. The hardened steel ensures that the precise threading and tolerances required for accurate powder drops will remain intact even with heavy use.

Performance & Functionality

The core job of the RCBS Quick Change Metering Screw Assembly is to allow for rapid and precise adjustments of powder charges. In this regard, it performs admirably. The mechanism for engaging and disengaging the screw is smooth, and once locked in, it maintains its position with zero detectable drift during dispensing. This consistency is paramount for handloaders who rely on exact powder charges for safe and accurate ammunition.

Its main strength lies in its quick change functionality, which significantly speeds up the reloading process when working with different powder types or charge weights. The assembly’s ability to hold its setting precisely means consistent powder drops, load after load. A potential, though minor, weakness could be the initial learning curve for perfectly aligning and locking the new screw assembly, but this is quickly overcome with practice.

Design & Ergonomics

The design of the RCBS Quick Change Metering Screw Assembly is fundamentally about utilitarian efficiency. Its construction from hardened steel gives it a solid, durable feel. The knurled or textured grip area on the adjustment knob is well-executed, providing a secure purchase even with slightly greasy hands, which can sometimes happen at the reloading bench.

Ergonomically, it’s designed to integrate seamlessly with the Uniflow powder measure. There’s no real learning curve beyond understanding the simple quarter-turn or similar locking mechanism. The precision of the threading is evident by the smooth, controlled rotation required to adjust powder volume. The black finish is practical and doesn’t detract from its functionality.

Durability & Maintenance

Given its construction from hardened steel, the RCBS Quick Change Metering Screw Assembly is built for a very long service life. Under normal reloading conditions, where it’s exposed primarily to propellant dust and occasional cleaning, I anticipate this component will last for many years, potentially decades. It is designed for a reloading environment, not extreme conditions, so prolonged exposure to harsh chemicals or abrasive materials is its primary concern.

Maintenance is refreshingly simple; typically, a quick wipe with a clean, dry cloth to remove any residual powder is all that’s needed. There are no complex parts to disassemble or lubricate. Potential failure points are minimal, likely limited to physical damage from dropping or overtightening, but its robust build makes these scenarios less probable.

Accessories and Customization Options

The RCBS Quick Change Metering Screw Assembly itself is an accessory, designed to enhance an existing powder measure. It does not come with additional accessories in the traditional sense. However, its purpose is to enable easier use of the Uniflow powder measure with different powder types and charge weights. The quick change nature means you can have multiple metering screws pre-set for common loads, effectively acting as interchangeable “modules.”

While the assembly itself isn’t customizable in terms of materials or design variations from RCBS, its true value lies in its interoperability with the RCBS Uniflow system. This allows reloaders to streamline their process without needing to re-zero or recalibrate extensively each time they switch powder dispensing configurations. It’s a functional upgrade, not an aesthetic one.
