The KleenBore .338 Caliber Rope Cleaner is an ultralight, manual pull-through firearm maintenance tool designed for rapid bore cleaning in the field and at the range. Built specifically for .338 calibre rifle barrels, it eliminates the need to carry sectional cleaning rods or loose patches during remote hunts or long shooting sessions. The cleaner operates on a multi-action, single-pass design that clears loose grit with an initial floss section, loosens hard fouling using integrated scrubbing bristles, and sweeps the bore clean with an oversized trailing body.

Key Features

• Multi-Action Single Pass: Combines an initial debris-clearing floss, embedded scrubbing bristles, and an expansive trailing body to scrub and wipe the bore in one continuous pull.
• High-Density Floss Area: Delivers 160 times more cleaning surface area than a single standard patch for thorough bore coverage.
• Calibre-Stamped Brass Weight: Features a drop weight clearly stamped with the .338 calibre size to simplify chamber feeding and quick identification in your kit.
• Washable and Reusable: Constructed from durable textiles for repeated washing and long-term field reuse.
• Bonus Maintenance Wipe: Includes a single BreakFree CLP packet for immediate bore lubrication and corrosion prevention.

Who is the Kleenbore .338 Caliber Rope Cleaner for?

• .338 Lapua Magnum long-range target shooters — provides 160 times more cleaning surface area than a standard patch to rapidly sweep powder fouling between long-distance shot strings without requiring a rigid cleaning rod.
• .338 Winchester Magnum heavy game hunters — delivers dedicated .338 calibre bore maintenance in an ultralight pull-through rope that packs easily into hunting gear for end-of-day barrel clearing in the field.

Less suitable for: Firearm bores smaller than .338 calibre due to the risk of severe bore jamming, bores larger than .338 calibre where loose fit prevents effective wall contact, or bench-level deep maintenance such as severe copper stripping and carbon ring cutting, which requires a rigid rod, solvent jag, and dedicated bronze bore brush.
