Brownells Heavy Weight Brush, Nylon, .50 Caliber Muzzleloader, 12 Pack

A 12-pack of Brownells Heavy Weight Brush brushes built for serious .50 caliber muzzleloader cleaning. If you shoot inline or traditional muzzleloaders, you know that black powder and saboted projectiles leave stubborn residue that demands an aggressive cleaning approach. These nylon brushes are designed to cut through that buildup without damaging the bore or rifling—a critical balance for maintaining accuracy and barrel life on your investment.

The nylon bristles are stiff enough to handle heavy fouling, yet engineered to be safe on rifled bores and smoothbore surfaces alike. The brass shank is looped and wound into a single solid piece, which means no weak joints or moving parts that could scratch your bore. That construction detail matters: a bristle brush is only as good as the hardware holding it together, and Brownells doesn't compromise there. The bristles resist deterioration when exposed to your preferred bore solvents, so they'll hold up through multiple cleaning cycles per shooting session.

The 12-pack format makes sense for serious muzzleloader shooters. You'll have backups on hand, and the cost-per-brush is lower than buying singles. At 3.26 inches overall with 8-32 male threading, these fit standard muzzleloader cleaning rod systems. Whether you're preparing for a season, stocking the range bag, or maintaining several rifles, this bulk set keeps you covered.
