Brownells Heavy Duty Cotton Round Patches, 2''/.40-.50 Cal, 1000 Pack

Brownells Heavy Duty Cotton Round Patches in 2-inch diameter, sized for .40 to .50 caliber firearms, are built for serious cleaning work. Whether you're breaking in a new barrel, running routine maintenance, or tackling heavy carbon buildup, these patches are engineered with a dual-sided design that handles both aggressive scrubbing and efficient solvent absorption. The 1000-pack format makes them economical for regular shooters and gun clubs that maintain multiple firearms.

The heavy-duty construction uses 10 oz. per yard, 104 thread count per square inch flannel glove cotton—the same material found in industrial workwear. One side is woven with a dense twill finish for scrubbing power; the other is fleeced to pull solvents and fouling out of bore cracks and hard-to-reach areas. This two-sided approach means you get both mechanical action and absorbency in a single patch, reducing the number of passes needed to clean a bore thoroughly.

Brownells designed these patches to work seamlessly with loop-style cleaning rod tips, so they seat securely and won't bunch or slip during the stroke. The 2-inch diameter fits standard bore guides and patch holders across the .40 to .50 caliber range, covering everything from .40 S&W and .45 ACP up to .458 SOCOM and larger rifle cartridges. For shooters who prefer custom patch sizes, the raw material is supplied in 7/8" × 6" strips, ready to cut to specification.

A 1000-pack is serious supply. If you shoot regularly, reload, or maintain a small armory, you'll appreciate having enough patches on hand to clean without rationing. Brownells packs them to protect from dust and damage, so they stay clean until you need them.

Frequently Asked Questions

Will these patches work with my .45 ACP or .44 Magnum revolver?

Yes. The 2-inch diameter fits the .40 to .50 caliber range, which covers .45 ACP handguns, .44 Magnum revolvers, and .458 rifles. Make sure your cleaning rod tip is loop-style so the patch seats properly without slipping.

What's the difference between the woven and fleece sides?

The woven twill side has a tight weave for scrubbing and mechanical cleaning action—ideal for removing stubborn carbon and fouling. The fleece side is highly absorbent and reaches into bore cracks and crevices, soaking up solvents and loosened debris. Using both sides in your cleaning routine speeds up the job and improves results.

Can I cut these patches to a smaller size?

Yes. Brownells supplies the material in 7/8" × 6" strips, so if you need a smaller patch for a handgun or want to customize the size, you can cut them to fit your specific cleaning needs.

Is 1000 patches enough to last?

That depends on how often you shoot and clean. Regular shooters and reloaders go through patches quickly, so a 1000-pack is a smart bulk buy that keeps you supplied without frequent reorders. One patch cleans one bore pass, so heavy barrel breaks-in or deep cleanings consume more patches than light maintenance.
