Viper Den Boresnake -.338-.340 Caliber Viper Rifle

The Hoppe's Viper Den Boresnake for .338–.340 caliber rifles delivers field-proven bore cleaning performance in a compact, portable design built for operators who demand reliability between full maintenance cycles. This boresnake addresses the core mission of magnum rifle shooters and precision marksmen who need fast, effective fouling removal without breaking down the firearm or hauling heavy cleaning kits to the range, field, or deployment.

Hoppe's boresnakes work through a simple but effective mechanical design: a weighted cord with a bronze brush section and felt patches that you pull through the bore in one smooth stroke. The bronze bristles engage copper fouling and carbon deposits, while the felt tail segments trap particulate matter and excess solvents. For magnum cartridges like .338–.340, bore diameter is larger and velocities are extreme, making residue management critical to sustained accuracy and barrel longevity.

The Viper Den version integrates this proven mechanism into a compact package that fits easily into a pack, range bag, or tactical load-out without sacrificing cleaning effectiveness. Law enforcement precision riflemen, military designated marksmen, long-range hunters, and competitive shooters benefit most from keeping a boresnake on hand for rapid maintenance in the field.
