The Proshot 45 Cal Black Powder Bore Brush is a dedicated barrel maintenance tool engineered to scrub heavy black powder fouling, carbon buildup, and lead residue from .45 calibre muzzleloaders and black powder firearms. Manufactured with oversized bronze bristles and a wound brass core anchored directly through a solid brass coupling, this mechanical bore brush delivers aggressive cleaning power without scratching steel rifling lands or damaging the muzzle crown.

Key Features

• Calibre-Specific Scrubbing: Sized specifically for .45 calibre bores to provide full bristle contact against the rifling grooves for thorough residue removal.
• Looped Brass Core: Built with a heavy-duty wound brass core integrated through the brass coupling to prevent the core and bristles from pulling loose during vigorous two-way scrubbing.
• Rifling-Safe Materials: Premium bronze bristles and a brass core provide firm mechanical scrubbing action while remaining softer than barrel steel.
• Heavy-Duty Threading: Fitted with a standard #10-32 male thread designed to thread directly into muzzleloader ramrods and heavy-duty range rods.

Who is the Proshot 45 Cal Black Powder Bore Brush for?

• Muzzleloader Shooters — Requires a heavy-duty black powder bore brush with a standard #10-32 male thread that mounts directly to muzzleloader ramrods to scrub corrosive residue from .45 calibre rifle and pistol barrels.
• Historical Reenactors and Target Competitors — Needs durable bronze bristles matched to .45 calibre dimensions to strip lead and black powder fouling during regular maintenance without damaging delicate historical rifling.

Less suitable for: Firearm barrels outside the .45 calibre operating envelope (such as sub-calibre .32/.36 bores or larger .50/.54/.58 bores), which require calibre-matched bore brushes to avoid bore binding or inadequate bristle contact; or shooters using modern cleaning rods with standard #8-32 female threads, who require a #10-32 female to #8-32 male thread adapter or an 8-32 threaded bore brush.
