RCBS Quick Change High Capacity Drop Tubes Review

Getting My Hands on the RCBS Quick Change High Capacity Drop Tubes

For years, the pursuit of precision in reloading has led me down many paths, often involving meticulous attention to detail with powder charges. While my trusty RCBS Uniflow powder measure has served me admirably for countless loads, I recently found myself grappling with the sheer volume of powder required for some of the larger rifle cartridges I’ve begun working with. Specifically, I was preparing to load for a .30-378 Weatherby, a cartridge that demands substantial powder charges, and the standard drop tube on my current powder measure was proving to be a bottleneck. It was clear I needed a solution that could handle larger volumes more efficiently.

My search led me to the RCBS Quick Change High Capacity Drop Tubes, a product designed to address precisely this need. These tubes are intended for reloaders who frequently set and dispense large rifle charges, aiming for consistency and accuracy. The idea of pre-setting charges for cartridges like the .30-378 Weatherby or even more extreme rounds like the 600 Nitro Express was incredibly appealing. I considered a few generic aftermarket drop tubes, but the reputation of RCBS for producing durable and reliable reloading equipment made their offering the most attractive.

Upon receiving them, my initial impression was one of robust simplicity. The tubes have a satisfying heft and a smooth, consistent internal diameter, hinting at their intended purpose of facilitating unimpeded powder flow. The green color is classic RCBS, and while purely aesthetic, it fits right in on my reloading bench. There was a palpable sense of relief mixed with anticipation; finally, a dedicated solution for those thirsty cartridges.

Real-World Testing: Putting RCBS Quick Change High Capacity Drop Tubes to the Test

My testing began on my dedicated reloading bench, a controlled environment where consistency is paramount. The primary goal was to assess how these tubes performed with large rifle powders, specifically those that are prone to bridging or static cling in smaller tubes. I paired them with the necessary RCBS Quick Change Drop Tube Adaptor for my existing Uniflow powder measure, a straightforward process that took mere minutes.

The first real test involved setting up a charge for the .30-378 Weatherby. I carefully adjusted my powder measure and dispensed a charge, observing the flow through the High Capacity Drop Tube. What immediately struck me was the significantly smoother and more complete discharge of powder compared to my old, smaller tube. There was virtually no powder left clinging to the inside walls, and the charge dropped cleanly into my sized case every time.

Over the subsequent weeks, I put these tubes through their paces with a variety of large-kernel rifle powders, including IMR 7828, Retumbo, and H1000. Each time, the performance was consistent. The RCBS Quick Change High Capacity Drop Tubes handled them all with grace, minimizing static cling and ensuring that the full intended charge made it into the case. I experienced no issues with bridging, even with the largest, fluffiest powders.

In terms of durability, these tubes have held up exceptionally well. After numerous uses, they show no signs of wear, no scratches, and the internal finish remains as smooth as day one. Cleaning is as simple as a quick wipe with a brush or cloth after a reloading session. They’ve been dropped on my concrete floor once (an inevitable occupational hazard for a gear specialist) and suffered no damage whatsoever, a testament to their solid construction. Compared to some flimsy plastic alternatives I’ve encountered over the years, these RCBS tubes feel built to last a lifetime.

Breaking Down the Features of RCBS Quick Change High Capacity Drop Tubes

The RCBS Quick Change High Capacity Drop Tubes are designed with a singular, critical purpose: to facilitate the accurate and consistent dispensing of large powder charges. Their design is elegantly simple, focusing on functionality and reliability. The core of their utility lies in their dimensions and materials, which are crucial for handling magnum rifle powder volumes.

Specifications

• Manufacturer: RCBS
• Quantity: 1 per package
• Color: Green
• Country of Origin: USA
• Capacity: While not explicitly stated in milliliters, these tubes are significantly wider in internal diameter than standard drop tubes, designed to accommodate larger powder volumes without restriction. This larger diameter is their key specification for high-capacity applications.
• Material: Constructed from a durable, smooth plastic that minimizes static electricity and ensures free powder flow. This material choice is critical for preventing powder from adhering to the tube walls.
• Compatibility: Designed to work with the RCBS Quick Change Drop Tube Adaptor, allowing seamless integration with RCBS Uniflow and Quick Change powder measures.

These specifications collectively contribute to the product’s effectiveness. The USA-made quality is evident in the finish, and the choice of material is paramount in preventing powder issues. The quick-change system is a practical feature that saves time and hassle during reloading sessions.

Performance & Functionality

The primary job of the RCBS Quick Change High Capacity Drop Tubes is to allow large powder charges to drop cleanly and consistently. In this regard, they excel. The wider internal diameter is the star of the show, preventing powders that are larger in kernel size or more prone to static from causing problems. I experienced absolutely zero powder hang-ups during my testing, which is a significant improvement over smaller diameter tubes.

The consistency of powder drops is directly impacted by how smoothly the powder exits the drop tube. With these larger tubes, the powder column exits more unimpeded, leading to a more uniform settling of powder in the case. This translates directly to more precise and repeatable loads downrange. Their performance exceeds expectations for their intended use, particularly when dealing with magnum rifle cartridges.

Design & Ergonomics

The design of these tubes is, as mentioned, straightforward and effective. The smooth, internal finish is key to their performance, ensuring that powder flows freely without obstruction. The external surface is also smooth, providing a comfortable grip when inserting or removing the tube from the adaptor. While there are no complex ergonomic features, the simplicity is its strength; there’s nothing to get in the way of its function.

The green color is a classic RCBS aesthetic, and while it doesn’t impact performance, it makes the tube easily identifiable on a busy reloading bench. The quick-change mechanism itself, which is part of the adaptor, is intuitive and requires no tools, making switching between drop tube sizes or types a matter of seconds.

Durability & Maintenance

Durability is a strong suit for these tubes. Made from robust plastic, they are designed to withstand the rigors of a reloading environment. I’ve already noted my accidental drop test, which they passed with flying colors. I anticipate these tubes will last for many years, possibly a lifetime, under normal use.

Maintenance is refreshingly simple. A quick wipe-down with a lint-free cloth or a soft brush is usually all that’s needed to remove any residual powder. For more stubborn powder residue, a gentle wash with soap and water followed by thorough drying will suffice. There are no complex parts to clean, and no special maintenance is required beyond basic cleanliness. The lack of moving parts means there are no potential failure points to worry about in terms of wear and tear.

Accessories and Customization Options

The RCBS Quick Change High Capacity Drop Tubes are designed to be used with the RCBS Quick Change Drop Tube Adaptor. This adaptor is the key accessory that allows these tubes to integrate with RCBS powder measures. The adaptor itself is a well-machined piece of equipment that securely holds the drop tubes.

While the tubes themselves aren’t customizable in terms of features, the quick-change system offers a form of practical customization. It allows reloaders to quickly swap between different sized drop tubes (standard, high capacity, etc.) depending on the powder and cartridge they are loading. This flexibility is invaluable for a reloader who works with a wide variety of cartridges.

Pros and Cons of RCBS Quick Change High Capacity Drop Tubes

Who Should Buy RCBS Quick Change High Capacity Drop Tubes?

The RCBS Quick Change High Capacity Drop Tubes are an absolute must-have for any reloader who frequently works with large-capacity rifle cartridges. This includes individuals loading for magnum hunting rounds, competitive long-range cartridges, or any application that requires dispensing substantial volumes of powder. If you’ve ever experienced frustration with powder sticking to smaller drop tubes or bridging with bulky rifle powders, these tubes are your solution.

Conversely, if your reloading primarily involves small pistol or .22 caliber rifle cartridges, the benefit of these high-capacity tubes will be minimal. In such cases, a standard drop tube might suffice. For those looking to maximize efficiency and consistency on larger loads, I would strongly recommend investing in the RCBS Quick Change Drop Tube Adaptor if you don’t already have it, as it unlocks the full potential of these excellent drop tubes.
