Breakthrough Clean BTCPS134500 Square Patches 270/357 Cal 1.75" 500ct

The Breakthrough Clean BTCPS134500 Square Patches deliver superior cleaning performance for .270 and .357 caliber firearms. These precision-cut patches maintain their structural integrity during cleaning, preventing fiber shedding that can interfere with barrel accuracy. Professional gunsmiths and competitive shooters rely on these patches for consistent bore maintenance.

What Makes This Different

Unlike round patches that can bunch up or leave gaps, these square-cut patches provide complete bore contact across the entire surface. The 1.75-inch dimension ensures proper fit for .270 Winchester and .357 Magnum chambers without excessive material that wastes cleaning solvent. Each patch maintains consistent thickness throughout the weave, eliminating thin spots that tear during extraction.

Key Features

• Square-cut design provides complete bore coverage without bunching
• 1.75-inch dimensions optimized for .270 and .357 caliber firearms
• High-tensile cotton weave resists tearing during cleaning rod extraction
• Low-lint construction prevents fiber residue in barrel rifling
• Absorbent material holds cleaning solvents without premature saturation
• 500-piece bulk packaging reduces per-patch cost for high-volume users
• Compatible with standard cleaning rods and jag attachments

These patches excel in both field cleaning scenarios and detailed maintenance sessions. The square geometry allows thorough cleaning of chamber areas where round patches often miss corners. Competition shooters appreciate the consistent cleaning results that maintain barrel accuracy between matches. Law enforcement armorers use these patches for departmental weapon maintenance programs where reliability cannot be compromised.
