Brownells Double-Tuff Bronze Rifle Brush 338 Caliber 12 Pack

The Brownells Double-Tuff Bronze Rifle Brush in .338 caliber is a heavy-duty bore cleaning tool built for shooters who demand results. Whether you're running a .338 Lapua, .338 Win Mag, or another cartridge in that bore diameter, this 12-pack gives you enough brushes to keep several rifles in rotation or to replace worn brushes without running short. Each brush features extra-thick phosphor bronze bristles that bite hard on stubborn carbon and fouling without marring your bore—a critical balance that separates a good brush from a mediocre one.

Brownells' Double-Tuff design means these brushes are engineered to handle aggressive scrubbing. The kinked wire construction allows you to apply real pressure during the cleaning stroke, which is exactly what you need when carbon buildup gets heavy. If you've ever fought with a weak brush that seems to glide over deposits instead of cutting them, you'll appreciate the extra durability and bristle stiffness here. The 3.25" length works well with standard rifle cleaning rod setups, and the 8-32 male threads fit common guide systems and rod handles.

A 12-pack is practical for the working shooter or gunsmith. Keep brushes staged for different rifles, or cycle through them as bristles gradually wear. Bronze bristles outlast brass in tough applications, and Brownells' extra-thick variant extends that advantage even further. This is functional, no-frills cleaning gear—exactly what belongs in a serious maintenance kit.

Frequently Asked Questions

What rifles will this .338 brush work with?

This brush fits any rifle chambered in .338 caliber, including .338 Lapua Magnum, .338 Winchester Magnum, and similar cartridges with that bore diameter. Verify your rifle's actual bore size before ordering if you're unsure.

Will these brushes scratch my rifle barrel?

No. The phosphor bronze bristles are softer than steel and are specifically designed not to mar bore surfaces, even with aggressive scrubbing. That said, always use a proper cleaning rod guide to center the brush and prevent contact with the bore walls.

What threads do these brushes use?

These brushes feature 8-32 male threads, which are standard on most rifle cleaning rods, guides, and handles. If your rod or handle uses a different thread size, verify compatibility before purchase.

Why get a 12-pack instead of just a few brushes?

A 12-pack is economical if you maintain multiple rifles or shoot regularly. Bristles gradually wear over time and heavy use, and having extra brushes on hand means you can replace them as needed without placing a new order. Many shooters also stage brushes for different rifles to streamline cleaning sessions.
