RCBS Quick Change Drop Tube Adapters Review

First Impressions of the RCBS Quick Change Drop Tube Adapters

As a long-time reloader, the pursuit of consistent and efficient powder handling is a constant endeavor. My bench is littered with tools that promise to shave seconds or improve precision, and it was in this spirit that I acquired the RCBS Quick Change Drop Tube Adapters. This seemingly simple set of adapters allows the integration of RCBS’s Quick Change (QC) funnel system, known for its drop tubes and adapters, with their popular Uniflow, Competition, and Lil’ Dandy powder measures. This particular adapter is a crucial bridge, enabling a faster transition between different powder types or lot numbers without the fuss of disassembling the entire powder dispenser.

My journey to these adapters began with a batch of notoriously fickle extruded powders. These powders, notorious for bridging and inconsistent flow, demanded a more direct and unimpeded path from the powder measure to the case mouth. The standard funnels often proved too wide, leading to static cling or simply not guiding the powder effectively. I was looking for a way to leverage the improved flow characteristics of dedicated drop tubes, but swapping them out on my Uniflow was a time-consuming process. While I considered some aftermarket solutions, the RCBS system promised a more streamlined, factory-supported approach that felt more reliable.

Upon receiving the RCBS Quick Change Drop Tube Adapters, my initial impression was one of typical RCBS no-nonsense functionality. The adapters themselves are small, green, plastic components, feeling robust enough for their intended purpose. There’s no complex machining or flashy design, just a straightforward design aimed at utility. They fit snugly into the existing powder funnel seating on my Uniflow, a reassuring sign of good manufacturing tolerances.

I had briefly looked at universal adapters that claimed to fit multiple powder measures, but the specificity of the RCBS design suggested a better, more secure fit within their own product ecosystem. My immediate reaction upon seeing how easily they seated was a quiet sense of satisfaction. This looked like a problem solved with minimal fuss.

Real-World Testing: Putting RCBS Quick Change Drop Tube Adapters to the Test

My testing grounds for these adapters were my reloading bench and the adjacent workshop. The primary scenario involved transitioning between different rifle cartridge loads, each requiring a distinct powder. I specifically targeted extruded powders, known for their tendency to hang up, alongside finer ball powders, to observe any flow differences. The adapters were integrated with my RCBS Uniflow powder measure and used with various caliber cases, from .223 Remington up to .30-06 Springfield.

During initial use, I noticed a distinct improvement in powder flow, particularly with the extruded powders. The drop tubes, when used with these adapters, provided a much cleaner and more direct path into the case neck, reducing spillage and static. Transitioning between powders was significantly faster; I could swap out a drop tube assembly in seconds rather than minutes. The adapters themselves showed no signs of stress or damage, even after repeated installation and removal over a weekend of intense reloading.

Extended use over several months has solidified the utility of these adapters. They’ve become a permanent fixture in my powder handling setup, allowing me to switch between my most frequently used powders with an ease I hadn’t previously experienced. I’ve intentionally left them installed for weeks at a time, exposed to the ambient dust and humidity of my workshop, and they’ve held up remarkably well. There are no cracks, no degradation in the plastic, and they continue to seat with the same snug fit.

In terms of maintenance, cleaning is as simple as wiping them down with a dry cloth or a touch of denatured alcohol if any powder residue builds up. Compared to the hassle of unscrewing and re-securing the entire powder funnel assembly of my Uniflow for every powder change, these adapters offer a substantial improvement in efficiency. I haven’t encountered any performance drop, and they continue to function precisely as intended, making them a worthwhile addition for any reloader using compatible RCBS powder measures and their QC funnel system.

First Use Experience

My initial testing took place directly on my reloading bench. I’d recently started loading for a new rifle cartridge that utilized a stick powder, and my existing powder funnel setup was proving inefficient. The fine grains of the extruded propellant tended to bridge in the funnel, requiring frequent tapping and leading to inconsistent charges. I installed one of the RCBS Quick Change Drop Tube Adapters onto my RCBS Uniflow powder measure, then attached a drop tube specifically designed for rifle cartridges.

The installation was straightforward; the adapter clicked into place with a satisfying firmness. When I dispensed the first charge of powder, the difference was immediately noticeable. The extruded powder flowed smoothly and directly into the case neck without hesitation. This single use confirmed the product’s primary function was met with flying colors.

I didn’t encounter any surprises or quirks during this initial phase. The adapter performed exactly as advertised, simplifying the powder dispensing process. It was an intuitive swap, and I felt comfortable using it immediately, understanding its purpose and function without needing an instruction manual.

Extended Use & Reliability

Over the course of several months, I integrated these adapters into my regular reloading routine for various rifle and pistol cartridges. My typical workflow involves loading in batches, often switching powders between sessions for different calibers. The adapters proved indispensable in this regard, significantly speeding up the process of caliber and powder changes. I’ve used them with coarse extruded powders, fine ball powders, and even some flake powders, and they have consistently provided a reliable connection.

Durability has been excellent. The green plastic shows no signs of weakening, cracking, or becoming brittle, even after being left installed on the powder measure for extended periods and occasional exposure to workshop conditions. There’s no noticeable wear on the internal or external surfaces where they interface with the powder measure or the drop tube. They’ve been dropped on the concrete floor more than once during reconfigurations, and each time, they emerged unscathed.

Maintenance is virtually non-existent. A quick wipe with a dry cloth is usually all that’s needed to remove any residual powder dust. If a particularly sticky powder were to leave residue, a very light application of denatured alcohol would suffice, but I’ve found this rarely necessary. The robust construction means they are resistant to damage from standard cleaning agents.

Compared to the integrated funnels that came with my powder measure, or even some other aftermarket funnel adapters I’ve experimented with in the past, these RCBS units are far superior for their intended application. They offer a secure, wobble-free connection that ensures consistent powder drop and easy swapping. They simply make the process of changing drop tubes much more practical and efficient for frequent use.
