The Pro-Shot .50 Caliber Black Powder Bore Brush is a purpose-built barrel cleaning tool engineered specifically to scrub corrosive fouling and residue from .50 calibre black powder rifles and muzzleloaders. Constructed in the USA, it features premium heavy-fill bronze wire bristles anchored to a solid brass core wire. To handle the unique directional demands of closed-breech muzzleloader cleaning, the brass core is looped and wound completely through the threaded coupling rather than crimped, preventing the head from detaching inside the barrel when reversing stroke direction. Its brass and bronze construction ensures effective mechanical cleaning without abrading or damaging steel rifling or muzzle crowns.

Key Features

• Dedicated Black Powder Construction: Sized and stiffened to scrub away stubborn fouling left by black powder and modern black powder substitutes in .50 calibre barrels.
• Wound-Through Coupling: Solid brass core is looped directly through the threaded base, eliminating the risk of bristle pull-out during mid-stroke or full-stroke direction reversals.
• Bore-Safe Materials: Heavy-fill bronze bristles and a solid brass core offer thorough scrubbing power while remaining softer than barrel steel to protect delicate rifling.
• Muzzleloader Thread Standard: Fitted with an industry-standard #10-32 male thread designed specifically for black powder range rods and cleaning rods.

Who is the Proshot 50 Cal Black Powder Bore Brush for?

• Australian muzzleloading target shooters — provides a dedicated .50 calibre bore brush with a standard #10-32 male thread that mounts directly to traditional range rods and withstands mid-stroke reversals without separating in closed breeches.
• Black powder hunters — delivers dense bronze bristles sized precisely for .50 calibre muzzleloader bores to efficiently remove corrosive black powder and propellant substitute fouling after field use.

Less suitable for: Firearm owners cleaning bores smaller than .45 calibre (which causes severe jamming and bore damage) or larger calibres such as .54 or .58 calibre (where scrubbing is loose and ineffective), who require calibre-matched bore brushes; and users of standard centrefire cleaning rods, who require a dedicated #8-32 to #10-32 thread adapter or standard #8-32 threaded brushes.
