Brownells Heavy Duty Square Cotton Patches, 1.75'', .338 Cal, 1000 Pk

Brownells Heavy Duty Square Cotton Patches in 1.75" size for .338 caliber rifles are engineered for shooters who work with hard-fouling cartridges and don't want to waste time swapping patches mid-cleaning session. Built from double-thick, soft-napped 100% cotton Canton flannel, these patches absorb more solvent and lift more carbon, copper, and powder residue per pass than standard patches—meaning fewer patches to accomplish the same job on heavily fouled bores.

The 1000-pack bulk format makes sense for serious rifle owners, competitive shooters, and anyone who runs centerfire rifle training regularly. Whether you're cleaning after a long range day, breaking in a new barrel, or maintaining a well-used hunting rifle, heavy-duty patches keep your workflow efficient. The 1.75" size pairs naturally with standard jags and loops for .338 caliber cleaning rod setups.

Brownells patches are trusted by gunsmiths and shooters for consistent quality and reliability. At this pack count, you'll have patches on hand for the season and beyond, so you're never caught short when the bore needs attention.

Frequently Asked Questions

Will these work with my .338 rifle cleaning rod?

Yes. The 1.75" square size is designed for .338 caliber rifles and works with standard cleaning rod jags and loop-style patch holders.

Why are these called heavy-duty patches?

They are made from double-thick cotton flannel, allowing each patch to hold more solvent and absorb more fouling than standard single-thickness patches. This means fewer patches needed to clean heavily fouled bores.

What's included in the 1000-pack?

The pack contains 1000 individual 1.75" square patches made from 100% cotton Canton flannel.

Can I use these for other calibers?

These patches are cut to 1.75" for .338 caliber use. For other calibers, you'd want to verify the appropriate patch size for your cleaning rod jag or loop.
