Bore Tech 338-41 Caliber 40'' Cleaning Rod

The Bore Tech 338-41 Caliber 40'' Cleaning Rod is a caliber-specific cleaning rod engineered for shooters who demand accuracy and safety in their bore maintenance routine. Built around a steel core matched to your cartridge, this rod handles the demands of centerfire rifle cleaning without the guesswork or damage that comes with generic solutions. Whether you're running a long-range precision rifle, a hunting gun, or a tactical setup, a properly sized cleaning rod matters—and Bore Tech's Proof Positive line delivers the engineering to back that up.

The rod's proprietary alloy ferrule and advanced coating are where this tool stands apart. That ferrule eliminates false readings when you're checking for copper fouling, so you're not over-cleaning or chasing phantom deposits. The chemically resistant coating resists wear and prevents debris from embedding into the rod surface, which keeps your bore cleaner longer and extends the life of the rod itself. The female-ended ferrule design is machined with an edge-free transition, so you can attach Proof Positive jags directly without needing adapters—a small detail that saves frustration during a cleaning session.

Comfort and control matter when you're running a rod down a rifle barrel, especially on longer cleaning sessions. The cushioned ball bearing handle gives you smooth, responsive feedback as the rod follows your rifling, and the ergonomic design prevents pressure points during use. Equally important: that padded handle is gentle on your rifle stock, so you can work without worrying about marring your wood or composite finish. The rod uses 8-32 threads, standard for .338 and .41 caliber applications.

Frequently Asked Questions

What caliber rifles does this rod work with?

This rod is sized for .338–.41 caliber rifles. If your rifle uses a different cartridge, you'll need the appropriate Bore Tech rod for your specific caliber.

Do I need adapters to attach jags to this rod?

No. The female-ended ferrule is machined to accept Proof Positive jags directly without adapters. Jags are sold separately.

Will this rod damage my rifle stock?

The cushioned handle is designed to be gentle on your stock. The padded grip and ball bearing system allow you to work with control and finesse, reducing the risk of marring wood or composite finishes.

What does "false copper reading" mean, and why does it matter?

Brass cleaning rods can leave tiny marks that look like copper fouling when you inspect your bore. Bore Tech's proprietary ferrule eliminates that false indication, so you know exactly when your bore is actually clean and don't waste time over-cleaning.
