RCBS Uniflow Powder Measure III Review

The Truth About Using the RCBS Uniflow Powder Measure III

My journey to finding a reliable powder measure led me to the RCBS Uniflow Powder Measure III. For years, I’d been piecing together loads with varying degrees of success, often battling inconsistency and the nagging worry of over- or under-charges. The need for a tool that could deliver precision, batch after batch, became paramount, especially as my reloading efforts moved beyond casual interest to a more rigorous pursuit of accuracy.

The moment this particular RCBS powder measure arrived, its heft and solid construction were immediately apparent. It felt less like a tool and more like a precision instrument, promising a level of performance that my previous, more rudimentary setups simply couldn’t offer. While I briefly considered some other well-regarded brands, the reputation of RCBS for durability and accuracy, coupled with the specific upgrades promised by the “III” model, made my choice clear.

Initial impressions were overwhelmingly positive; the machined surfaces felt smooth, the hopper sealed well, and the overall build quality suggested it was designed to withstand years of use. There was an immediate sense of relief, a quiet confidence that this might just be the solution I had been searching for.

Real-World Testing: Putting RCBS Uniflow Powder Measure III to the Test

First Use Experience

My testing began on my dedicated reloading bench, a space I’ve meticulously set up to minimize variables. The environment is controlled, with steady lighting and temperature, allowing me to focus solely on the performance of the powder measure itself. I tested it with a variety of common propellant types, including both fine-grained flake powders and denser extruded varieties, to see how it handled different densities and flow characteristics.

The operation was remarkably smooth from the outset. I found that after a brief adjustment period, familiarizing myself with the rotor’s travel and the hopper’s capacity, the measure became an intuitive extension of my hand. There were no immediate issues or surprising quirks; the initial setup was straightforward, and the process of dialing in charges felt precise and repeatable.

Extended Use & Reliability

After weeks of consistent use, filling it over two dozen times each session, the RCBS Uniflow Powder Measure III continues to perform admirably. Its durability is evident; there are no signs of stress, wear, or degradation in its precise machining. The tight tolerances that were apparent upon arrival have remained, ensuring the consistent throws I’ve come to rely on.

Maintenance has been straightforward, which is a significant advantage. A quick wipe-down after each major reloading session, and occasional deeper cleaning of the internal mechanism, has kept it performing optimally. I haven’t experienced any powder bridging or sticking, even with less forgiving powder types, thanks to the NG resistant anti-static threaded hopper. This ease of maintenance, compared to some older, more finicky measures I’ve used, is a real boon for efficiency.

Breaking Down the Features of RCBS Uniflow Powder Measure III

Specifications

The RCBS Uniflow Powder Measure III boasts a set of specifications that underscore its commitment to precision and versatility. Its 0.5 to 95 grains dispensing range is exceptionally broad, capable of handling everything from pistol cartridges to larger rifle loads with remarkable accuracy, often within 0.1 grain to 0.3 grain. This wide range means a single unit can serve multiple reloading needs, eliminating the need for specialized measures for different calibers.

The NG resistant anti-static threaded hopper is a standout feature. It has a generous capacity, holding approximately half a pound of extruded powder or one-third pound of flake powder, minimizing the frequency of refills during extended reloading sessions. The threaded design is a practical improvement, making disassembly for cleaning quick and easy, a welcome change from older, more cumbersome designs.

Performance & Functionality

The primary function of any powder measure is accurate dispensing, and this RCBS unit excels. The machined reference surfaces for exacting tight tolerances are not just marketing jargon; they translate directly into consistent, repeatable powder charges. I’ve consistently achieved throws that are well within the advertised accuracy, which is critical for handloading accurate ammunition.

Its strengths lie in its precision and the ease with which it can be adjusted for different powder weights. The ability to change charge weights without emptying the hopper is a significant time-saver, particularly when working up loads for multiple firearms. If there’s a minor weakness, it might be that achieving the absolute absolute finest level of precision (e.g., +/- 0.05 grains) would still require trickle charging for the most demanding applications, but for general reloading purposes, its accuracy is outstanding.

Design & Ergonomics

The design of the RCBS Uniflow Powder Measure III is robust and functional. The green, powder-coated cast iron base provides a stable foundation, preventing any rocking or movement during operation, which is crucial for consistent dispensing. The anti-static hopper not only resists powder buildup but also contributes to a cleaner workspace.

Ergonomically, the large crank handle and smooth rotor action make it comfortable to use for extended periods. The markings on the adjustment mechanism are clear and easy to read, facilitating quick and accurate setting of desired powder charges. While not a flashy design, its utilitarian aesthetic speaks to its purpose: to be a reliable workhorse in the reloading process.

Durability & Maintenance

Built with USA manufacturing standards, the RCBS Uniflow Powder Measure III feels exceptionally durable. The cast iron base and precision-machined internal components suggest a product designed to last a lifetime. I anticipate minimal wear and tear under normal usage conditions, which for me means regular reloading sessions for various firearms.

As mentioned, maintenance is a breeze. The threaded hopper design allows for easy removal and cleaning, preventing any powder accumulation that could compromise accuracy over time. A simple brush and a damp cloth are usually all that’s needed to keep it in top condition.

Accessories and Customization Options

While the RCBS Uniflow Powder Measure III is a complete unit on its own, RCBS does offer accessory items that can further enhance its utility. For instance, one might opt for a second metering cylinder for dedicated pistol or rifle powders, allowing for even faster changeovers without the need to empty and clean the original cylinder. A drop tube can also be a useful addition for certain powder types or case designs to ensure powder settles properly before seating a bullet.

Pros and Cons of RCBS Uniflow Powder Measure III

Who Should Buy RCBS Uniflow Powder Measure III?

This powder measure is ideal for the serious handloader who prioritizes accuracy and consistency above all else. Whether you reload for precision rifle shooting, competitive pistol disciplines, or simply want the most reliable ammunition possible for hunting or self-defense, this unit will serve you exceptionally well. It’s also a great choice for those who reload for multiple calibers and appreciate the ability to quickly adjust charge weights.

Those who are just beginning their reloading journey and are on a very tight budget might want to consider a more basic model initially, as this is an investment in precision. However, if you plan to reload for the long haul, buying this powder measure now will save you the cost and frustration of upgrading later. Essential accessories would include a trickle charger for those seeking the absolute ultimate in precision for match-grade loads, and potentially an extra metering cylinder if you frequently switch between very different types of powder or calibers.
