Hoppe's Boresnake Den- .338 .340 Caliber Rifle

The Hoppe's Boresnake Den .338 .340 Caliber Rifle cleaning kit delivers fast, efficient bore maintenance in a purpose-built transport case designed for field and range use. This compact carrying system houses a complete one-pass bore cleaning solution, combining an integrated bronze brush with a tail patch system that simultaneously scrubs carbon fouling and removes debris in a single pass—the foundation of Hoppe's reputation as the fastest bore cleaning method available.

The Boresnake Den case itself measures 4.15 x 2.3 x 1.4 inches and weighs only 0.16 lbs, making it an ideal complement to a range bag, patrol pack, or rifle case. The snap-fit lid doubles as a pull handle for retrieval, while the clear polymer housing provides visual confirmation that your cleaning kit is present and ready. This design eliminates the need for traditional multi-piece cleaning rod setups, reducing maintenance time between firing sessions while maintaining thorough carbon removal critical for accuracy and barrel longevity in .338 and .340 caliber rifles.

This system is engineered for shooters—law enforcement, military personnel, and serious hunters—who operate large-bore rifles chambered in .338 Winchester Magnum, .340 Weatherby Magnum, and similar cartridges. The bronze brush configuration addresses the fouling patterns specific to magnum rifle cartridges, which produce denser carbon deposits than standard rifle rounds. Operators who maintain rifles in field conditions, conduct regular accuracy verification, or transition between ammunition types benefit from the speed and simplicity of a dedicated bore cleaning solution that stays packed and travel-ready.
