J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack Review

The J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack Made a Bold First Impression

As a seasoned outdoor and tactical gear specialist, maintaining my firearms is paramount. Copper fouling, especially in smaller calibers like .17, can significantly impact accuracy if left unchecked. That’s why I was intrigued by the J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack, promising effective copper removal without the misleading blue-green residue that plagues traditional brass-core brushes.

My interest in this product stemmed from a recurring issue with my .17 HMR rifle. Even after thorough cleaning with standard brushes and solvents, I often encountered “false positives” – those frustrating blue-green streaks on patches suggesting persistent copper fouling, even when the bore was seemingly clean. This left me second-guessing my cleaning regimen and questioning the rifle’s accuracy potential. The J. Dewey brushes, with their ammonia-safe aluminum and nylon construction, seemed like the perfect solution.

Upon receiving the J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack, I was immediately impressed with the apparent quality. The brushes felt sturdy, and the nylon bristles were densely packed, suggesting effective scrubbing power. The aluminum core and coupling, a departure from the usual brass, gave a sense of innovation and purpose.

Compared to generic brass-core brushes I’d been using, the J. Dewey brushes felt like a significant upgrade. I had considered other copper-specific cleaning tools, like bore snakes with embedded brushes or more aggressive chemical solvents, but the J. Dewey brushes seemed like a balanced approach – effective mechanical cleaning with a design that avoided the common pitfalls of brass contamination. I chose the J. Dewey brushes specifically to eliminate false positives during the cleaning process.

My first impression was one of cautious optimism. The J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack appeared well-made and thoughtfully designed to address a specific problem I faced. I was eager to put them to the test and see if they lived up to their promise of cleaner, more accurate copper removal.

Real-World Testing: Putting J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack to the Test

First Use Experience

My initial testing of the J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack took place at my home cleaning bench after a day of varmint hunting with my .17 HMR. The rifle had seen approximately 100 rounds, so I expected a fair amount of copper fouling. Using my regular bore solvent, I ran the J. Dewey brush through the bore.

The brush moved smoothly, but firmly, down the barrel. What immediately stood out was the lack of the telltale blue-green tint on the first few patches. This was a significant difference from my experience with brass brushes. I experienced no issues on the first run.

Extended Use & Reliability

After several weeks of regular use following range sessions and hunts, the J. Dewey 17 Caliber 5-40M Copper Elimnator Bore Brush 3/Pack continues to impress. The brushes have held up remarkably well, showing no signs of bristle degradation or loosening of the aluminum coupling. Maintaining the J. Dewey brushes is also incredibly simple.

I simply clean them with solvent after each use and allow them to air dry. Compared to my previous brass brushes, the J. Dewey brushes offer a much cleaner cleaning experience and provides confidence in copper removal. I found that I can achieve a truly clean bore in fewer passes and without second-guessing the results.
