Brownells Standard Line Stainless 35/38/357 Caliber Rifle Brush 12Pack
A 35/38/357 caliber rifle brush is an essential consumable for serious shooters who go through more brushes than most folks realize. The Brownells Standard Line Stainless 35/38/357 Caliber Rifle Brush 12-pack delivers bulk economy without compromise on build quality—these are the same top-shelf brushes Brownells uses in their own shop, now packaged in quantities that make sense for active reloaders and gunsmiths who wear out cleaning gear regularly.
These brushes use stainless steel bristles backed by a one-piece looped and wound steel shank—not a cheapo twisted-together design that fails mid-cleaning. The aggressive stainless bristles excel at scrubbing out lead buildup, stubborn fouling, and light rust from bore surfaces, making them particularly useful for precision rifle barrels or firearms that see heavy use. Because stainless acts more aggressively than bronze, it cuts faster, but that same action means sustained use can accelerate bore wear over time—a tradeoff worth understanding if you're running high volumes downrange.
At 3.27 inches overall, these brushes fit standard .17 and .20 caliber rods with 5-40 threads, and larger calibers (including your 35/38/357 magnums) with 8-32 threads. The 12-pack format makes sense if you're maintaining multiple firearms, sharing a reloading space, or simply tired of running out mid-cleaning session. Stock a handful and stop worrying about brush inventory.

Frequently Asked Questions
What rod thread size do these 35/38/357 brushes use?
These brushes feature 8-32 threads, which is the standard for larger rifle calibers including 35/38/357.
When should I use stainless steel bore brushes instead of bronze?
Stainless steel brushes deliver aggressive cleaning action ideal for heavily leaded bores, stubborn fouling, or light rust. Keep in mind that this aggressive action accelerates wear on barrel steel, so they're best reserved for deep cleaning rather than routine maintenance.
Why buy a 12-pack if I only have one rifle?
Bore brushes are consumables that wear out with use. A 12-pack is economical for shooters who maintain multiple firearms, work in a shop, or reload in volume. You'll go through brushes faster than you think once you start shooting seriously.
Is the shank design important?
Yes. Brownells uses a one-piece looped and wound shank rather than two pieces twisted together and chopped off. This design is more durable and resists separation during aggressive scrubbing.
