Brownells Standard Line Stainless 338 Caliber Rifle Brush 12 Pack

The Brownells Standard Line Stainless 338 Caliber Rifle Brush 12 Pack gives you a practical bulk supply of quality bore brushes built for serious cleaning work. Whether you're maintaining a 338-caliber rifle after a heavy range day or tackling a gun that's seen hard use and carbon buildup, stainless steel bristles deliver the aggressive scrubbing action needed to cut through lead, copper, and rust fouling. The one-piece, looped-and-wound shank is tougher than twisted designs—it won't separate or fail mid-stroke. Buy them in a dozen and keep them on hand: you'll use them faster than you'd expect, whether you're a gear-focused shooter managing your own maintenance or a shop operator who goes through brushes regularly.

Stainless steel is the right choice when you're facing severely fouled or rusted bores. The bristles bite harder than softer bronze or brass, so you get faster, more thorough cleaning. That said, the trade-off is real: aggressive bristles can accelerate wear on barrel steel with repeated use, so reserve these for problem bores and heavy fouling rather than routine maintenance on a clean gun. Pair them with your favorite bore solvent and a cleaning rod, and you're set to restore a tough bore to shootable condition.

The 3.27-inch length and industry-standard 8-32 threads fit most 338-caliber rifles and common cleaning rods, making them compatible across your collection. A dozen brushes means you won't run short mid-project or worry about replacing worn bristles for a season.

Frequently Asked Questions

Will these 338 rifle brushes fit my cleaning rod?

Yes. These brushes use a standard 8-32 thread, which is the industry-standard fit for .338-caliber rifles and cleaning rods. Confirm your rod also uses 8-32 threads to ensure compatibility.

When should I use stainless steel brushes instead of brass or bronze?

Stainless steel bristles are designed for heavily fouled, leaded, or rusted bores where a softer brush won't cut through the buildup. The aggressive scrubbing action makes them ideal for problem guns. However, because they wear barrel steel faster with repeated use, reserve them for deep cleaning and maintenance, not routine care on a clean bore.

Why buy a 12-pack?

Bore brushes wear out and get used up faster than many shooters expect, especially in a shop or if you maintain multiple rifles. A dozen lets you replace worn brushes without frequent reorders and keeps extras on hand when you need them.

Is the shank durable?

Yes. The shank is one-piece, looped and wound construction rather than two pieces twisted together and cut off. This design is stronger and won't separate during use.
