Brownells Heavy Duty Cotton Round Patches, 1.5''/.35-.40 Cal, 1000 Pk

Keeping your rifle barrel clean starts with the right patch—and the Brownells Heavy Duty Cotton Round Patches are built for serious shooters who refuse to compromise on bore care. These 1.5-inch patches fit .35-.40 caliber firearms and come in a 1000-pack that'll last through countless cleaning sessions. Made from heavy flannel glove cotton, they're engineered to handle aggressive scrubbing without falling apart mid-pass.

What makes these patches stand out is the two-sided design: one side is fleeced for maximum absorbency, while the other is a dense woven twill that actually scrubs the bore and gets into the cracks where carbon and fouling hide. Whether you're breaking in a new barrel, deep-cleaning after a long hunt, or maintaining match-grade accuracy, the dual texture does real work. The 10 oz. per yard construction with 104 threads per square inch means these patches won't shed fibers or disintegrate under pressure—they stay intact even when you're being thorough.

The round format works perfectly with loop-style cleaning rod tips, and you can trim them further if you need a smaller patch for tight bores or specific cleaning tasks. A 1000-pack is a solid investment for anyone with multiple rifles or who shoots frequently; you'll use them consistently and never run short mid-season.

Frequently Asked Questions

What calibers do these patches fit?

These patches are sized for .35-.40 caliber rifles. The 1.5-inch round shape is designed to work with loop-style cleaning rod tips in that bore diameter range.

Can I trim these patches smaller?

Yes. While they come cut to 1.5 inches, you can further trim them to fit tighter bores or specific cleaning needs if necessary.

Why two different sides?

The fleece side is highly absorbent and picks up solvents, oils, and fouling, while the dense woven twill side actively scrubs the bore and reaches into cracks where carbon deposits hide. This dual approach makes for faster, more effective bore cleaning.

Is a 1000-pack overkill for one rifle?

Not if you shoot regularly or own multiple rifles in that caliber range. A serious shooter can go through patches quickly, and buying in bulk keeps your cost per patch low and ensures you're never caught short during a cleaning session.
