Pro-Shot 338NR .338 Caliber Rifle Bore Brush Nylon Bristles

The Pro-Shot 338NR bore brush delivers thorough cleaning for .338 caliber rifles without the aggressive scrubbing that damages barrel rifling. This precision-engineered cleaning tool combines nylon bristles with a brass core to remove fouling while protecting your barrel's interior finish.

What Makes This Different

Unlike bronze brushes that can scratch delicate barrel surfaces, the 338NR uses specially formulated nylon bristles that maintain their shape through hundreds of cleaning cycles. The brass core provides structural integrity while remaining softer than steel barrels. This combination removes carbon buildup and copper fouling without the risk of wear patterns that affect accuracy over time.

Key Features

• Nylon bristles preserve barrel rifling and prevent scratching
• Brass core construction resists bending and maintains brush shape
• #8-32 thread pitch fits standard cleaning rod systems
• .338 caliber specific sizing for optimal bore contact
• Chemical-resistant bristles withstand all common solvents
• Precision-wound bristles ensure even cleaning coverage
• Corrosion-resistant materials for long service life

The 338NR performs effectively with both traditional powder solvents and modern copper-removing chemicals. Competition shooters rely on nylon brushes to maintain sub-MOA accuracy between matches, while hunters appreciate the gentle cleaning action that preserves barrel life. The brush removes stubborn fouling without the aggressive action that can accelerate throat erosion in magnum cartridges.
