The Pro-Shot .58 Caliber Black Powder Bore Brush is a dedicated mechanical cleaning accessory designed to scrub corrosive black powder residue, heavy fouling, and lead build-up from .58 calibre muzzleloaders, muskets, and replica barrels. Built specifically for black powder maintenance, it features premium bronze bristles anchored to a solid brass core that is looped directly through a threaded brass coupling to prevent bristle loss or core detachment during back-and-forth scrubbing.

Key Features:

• Calibre-Specific Cleaning: Sized precisely for .58 calibre (approximately 14.7 mm) bores, providing optimal bristle tension against the rifling grooves without binding.
• Bore-Safe Metallurgy: Manufactured with softer-than-steel bronze bristles and a solid brass core to prevent scratching, gouging, or premature wear on steel barrels and muzzle crowns.
• Looped Brass Tip: Incorporates a looped end on the brass core rather than sharp cut wire ends to protect the barrel interior during insertion and extraction.
• Integrated Coupling Design: The wire core is looped and wound directly through the coupling, preventing separation when reversing direction inside tight, fouled bores.
• Standard Black Powder Threading: Fitted with a #10-32 male thread to directly mate with standard black powder ramrods and range rods.

Product Specifications:

• Calibre Compatibility: .58 Caliber (approx. 14.7 mm bore diameter)
• Thread Interface: Standard #10-32 male thread
• Core Material: Solid brass
• Bristle Material: Premium bronze
• Packaged Weight: Approximately 14 g (0.5 oz)
• Overall Brush Length: Approximately 50 mm to 75 mm
• Operation: Non-powered / manual operation (exempt from Australian electrical safety regulatory schemes)

Who is the Proshot 58 Cal Black Powder Bore Brush for?

• Muzzleloading rifle shooters and black powder club members — Requires dedicated cleaning tools sized to .58 Caliber (approx. 14.7 mm bore diameter) to exert proper surface contact against deep rifling grooves and directly attach to standard black powder range rods via the #10-32 male thread interface.
• Historic re-enactors maintaining .58 calibre Enfield or Springfield replicas — Relies on a non-marring bronze bore brush weighing approximately 14 g to mechanically strip corrosive fouling out of .58 Caliber barrels without damaging the historically accurate steel rifling.

Less suitable for: Firearm bores measuring smaller than .58 calibre (where the oversized bristles will not fit) or larger than .58 calibre (such as .62 or .75 cal muskets, where the brush cannot make sufficient contact with bore walls, requiring dedicated larger-diameter bore brushes), as well as standard cleaning rods with #8-32 female threads unless used with an 8-32 to 10-32 thread adapter.
