RCBS .17-.20 Caliber UPM Drop Tubes Review

Let’s Dive into RCBS .17-.20 Caliber UPM Drop Tubes

In the realm of precision reloading, every detail matters. The RCBS .17-.20 Caliber UPM Drop Tubes are designed to bridge the gap between your Uniflow Powder Measure and those tiny, finicky cases of .17 and .20 caliber cartridges. These aren’t flashy, but they promise to streamline the powder-charging process, minimizing spills and maximizing accuracy.

My journey to these drop tubes began with a frustrating problem: consistently and cleanly charging .17 Hornet cases. Standard powder measures often dribble powder around the case mouth, especially with small calibers. I needed a solution to eliminate wasted powder and inconsistent charges.

My first impression upon unboxing was “simple, yet effective.” The green color is distinctive, the material seems robust, and the finish is clean. It’s a single piece, so there’s not much to it aesthetically, but functionality is paramount.

I considered alternatives like using a powder trickler exclusively, but that’s time-consuming. Other drop tubes exist, some custom-made, but RCBS has a reputation for reliability, and the price point of $10.99 made this a low-risk investment. I chose these over other options due to the RCBS brand’s solid track record and the precisely sized opening for the tiny cases I work with.

I was cautiously optimistic. I hoped these drop tubes would deliver on their promise of improved powder flow and reduced spills.


Real-World Testing: Putting RCBS .17-.20 Caliber UPM Drop Tubes to the Test

First Use Experience

My primary testing ground was my reloading bench, preparing .17 Hornet rounds for varmint hunting. The bench can get dusty, but conditions were otherwise controlled indoors. I specifically focused on how cleanly the powder flowed into the diminutive case mouths.

The tubes performed well, even with fine-grained powders like Hodgdon H110. There was a noticeable decrease in powder spillage compared to trying to directly charge cases from the Uniflow. No time was needed to get used to the tubes, installation was easy; simply screw in the drop tube.

The only initial issue was a bit of static cling causing some powder to stick to the inside of the tube, this was easily solved with a wipe down using an anti-static wipe.

Extended Use & Reliability

After several months of consistent use, the RCBS .17-.20 Caliber UPM Drop Tubes have proven their worth. They are a simple, but valuable addition to my reloading setup. The tubes show no signs of wear and tear.

Cleaning is simple; a quick wipe with a dry cloth removes any residual powder. The tube is sturdy enough to resist bending or breaking. The tubes have drastically outperformed my previous method of carefully pouring powder with a spoon.
