5-Pack .50 Caliber Cotton Bore Mop

In stock
SKU: MP-0001-050-p5

A .50 caliber muzzleloader bore holds a massive amount of fouling - and black powder residue starts corroding the steel within hours if left uncleaned. This .50 caliber cotton bore mop is built to absorb it all. After brushing, run this densely packed 100% cotton mop through with hot soapy water or bore solvent to pull out dissolved powder residue in one pass. Follow with a dry mop, then an oiled one to seal the bore.

Muzzleloader shooters know that cleaning can't wait - every hour of delay means more corrosion eating into the steel. A bore mop holds significantly more liquid than a patch, which means fewer passes and faster gun cleaning when time matters. In the field after a hunt, a mop soaked with bore solvent is the quickest way to stabilize the barrel until you can do a full cleaning at home.

Wash with hot water after each black powder session, air dry, and it's ready again. This bore cleaning mop earns its spot in every muzzleloader owner's gun cleaning kit - the bore is too big and the stakes too high to skip the mop step.

What thread size does a .50 caliber muzzleloader bore mop use?
Most .50 caliber muzzleloader bore mops use 10-32 threads - the standard for muzzleloader cleaning accessories. This is different from the 8-32 threads used by centerfire rifle mops. Your muzzleloader's ramrod typically accepts 10-32 threaded attachments directly, so the mop threads on without adapters.
What is the best way to use a bore mop when cleaning a muzzleloader?
Soak the mop in hot water or black powder solvent and run it through the barrel from breech to muzzle. The mop absorbs the water-soluble fouling that black powder and substitutes leave behind. Repeat with fresh solvent until the mop comes out clean. Then run a dry mop through to remove moisture, and finish with a lightly oiled mop to prevent rust. Muzzleloader barrels corrode fast if left wet.
Can I use a regular bore cleaner on my muzzleloader, or do I need a special solvent?
Black powder and Pyrodex leave sulfur-based fouling that standard smokeless-powder bore cleaners cannot dissolve. Use a black-powder-specific solvent or hot soapy water for these propellants. If you shoot modern substitutes like Triple Seven, some standard cleaners work, but check the manufacturer's recommendation. The bore mop is just the delivery tool - the solvent choice is what matters for muzzleloaders.
How often should I replace my .50 cal bore mop?
Muzzleloader cleaning is tough on bore mops because black powder fouling is heavy and corrosive. Expect to replace the mop more frequently than you would for a centerfire rifle - roughly every 8-12 cleaning sessions with heavy use. When the cotton thins out and the mop slides through without absorbing, it's time. Washing between sessions with hot water extends the mop's life.
Why is it important to dry the bore after mopping a muzzleloader?
Muzzleloader barrels are often made from carbon steel without the corrosion-resistant coatings found on modern centerfire rifles. Any moisture left in the bore after cleaning starts forming rust within hours. Run a dry mop through after cleaning, then follow with an oiled mop to leave a protective film. Store the muzzleloader muzzle-down so residual moisture doesn't pool in the breech plug area.
