Breakthrough Clean BTCPS13450 Square Patches 270/357 Cal 1.75" 50ct

The Breakthrough Clean BTCPS13450 Square Patches deliver superior cleaning performance for .270 and .357 caliber firearms. These precision-cut patches maintain consistent contact with bore surfaces, ensuring thorough removal of fouling and residue that standard round patches often miss.

What Makes This Different

Unlike traditional round patches that can bunch up or leave corners uncleaned, these square-cut patches provide four distinct edges that conform to rifling grooves. The 1.75-inch dimensions offer optimal coverage for medium-bore calibers while preventing jamming in the bore. Each patch features lint-free construction that won't leave fibers behind, maintaining bore integrity shot after shot.

Key Features

• Square-cut design provides superior bore contact and cleaning coverage
• 1.75-inch dimensions optimized for .270 Winchester and .357 Magnum calibers
• Lint-free cotton construction prevents fiber contamination
• 50-patch count provides extended cleaning sessions
• Compatible with all standard cleaning solvents and oils
• Pre-cut edges eliminate fraying and ensure consistent performance
• Absorbent material holds cleaning solutions effectively

These patches excel in both field cleaning and detailed maintenance routines. The square geometry allows shooters to reach bore corners that accumulate stubborn copper and carbon deposits. Competition shooters benefit from the consistent patch-to-bore contact that ensures repeatable cleaning results between strings of fire. The lint-free material works effectively with aggressive copper solvents without breaking down or leaving residue.
