The Pro-Shot Bronze Bristle Chamber Brush (Pro-Shot part no. 338BC) is sized for .338 caliber and 8.7mm chambers, built to scrub carbon and fouling out of the chamber walls and locking-lug recess where a standard bore brush can’t reach. Bronze bristles are firm enough to break loose baked-on carbon without damaging chamber steel, making this a safe daily-use tool rather than something reserved for occasional deep cleaning. Pro-Shot manufactures its chamber brushes to fit standard cleaning rod and cable threads, so it drops into an existing cleaning routine without needing new hardware. Owners of .338-class rifles who want a thorough chamber cleaning alongside their bore work will want one of these on hand.
