Brownells Chamber Brush, Stainless Steel37/.357 Cal Revolver,12 Pack

Revolver shooters know that cylinder chambers take a beating—especially when you're running full-power loads after a session with lighter wadcutters. Brownells' stainless steel chamber brushes tackle the stubborn fouling and leading that handgun cleaners alone can't budge. This 12-pack gives you enough brushes to clean all six chambers on a revolver, plus spares for your range bag or rotation through your rotation of .37 and .357 caliber guns.

Built from tough stainless steel, these brushes are engineered to scrub out hard carbon and lead deposits without damaging chamber walls. They're especially valuable when you've been cycling full-power ammunition and need to prep your revolver for the next range session or hunt. Unlike softer materials that wear out or leave residue behind, stainless stands up to aggressive cleaning and won't rust in your cleaning kit.

Whether you're a revolver enthusiast running a mix of load weights or a hunter moving between wadcutter practice and hunting rounds, keeping cylinder chambers clean is essential for reliable function and longevity. This multi-pack takes the guesswork out of chamber maintenance—you'll always have a fresh brush on hand.

Frequently Asked Questions

Will these chamber brushes work on my .357 Magnum revolver?

Yes. These brushes are sized for both .37 and .357 caliber chambers, so they'll fit standard revolvers in those calibers.

Why do I need chamber brushes if I already have standard gun cleaning brushes?

Chamber brushes are specifically designed to fit inside revolver cylinder chambers and scrub walls directly—something a general-purpose bore brush can't do effectively. They're especially useful after shooting full-power loads or when leading and fouling have built up from mixed ammunition types.

Why is a 12-pack useful for cleaning one revolver?

The multi-pack lets you have a fresh brush available for each chamber, speeding up your cleaning routine. You can also keep spares in different locations—your cleaning kit, range bag, or truck—without running short.

Are these brushes safe for stainless steel revolver cylinders?

Yes. Stainless steel brushes won't scratch or damage stainless steel chambers. They're tough enough to clean hard fouling but won't harm the cylinder.
