Streamline bore care and protect accuracy with the Breakthrough Clean Technologies Square Cotton Patches (1-3/4" x 1-3/4"). Sized precisely for .270–.357 caliber firearms, these tight-weave, low-lint cotton patches deliver positive rifling contact, excellent solvent uptake, and smooth oil application. The convenient 50-count pouch is perfect for range bags, cleaning mats, and quick top-offs between matches or hunts.

Why These 1.75" Patches Are a Smart Upgrade

• Optimized sizing for .270–.357: Confident 360° engagement in .270 Win, .280 Rem/7mm-08 (with appropriate jag), .30-30, .308 Win/7.62 NATO, .30-06, .300 BLK, .300 Win Mag, .338, and .357 Mag/.38 Spl platforms when paired with the correct jag or loop.

• High-absorbency cotton: Premium fibers hold solvent and oil to lift carbon, powder, and light copper fouling—fewer passes, better results.

• Low-lint finish: Designed to minimize stray fibers, leaving the bore bright and uniform.

• Uniform cut & thickness: Predictable push resistance makes patch/brush cycles consistent and repeatable.

• Grab-and-go 50 pack: Ideal for weekend training, hunting trips, and compact field kits.

Faster, Cleaner Results for Mid-Large Bores

These 1.75" squares deliver the coverage sweet spot for .270–.357 bores—large enough to wipe lands and grooves thoroughly, compact enough to maintain smooth travel through the bore. Paired with a matching jag, they push solvent efficiently, carry fouling out of the barrel, and finish with a thin, even oil layer to fight corrosion.

How to Use (Best Practices)

1. Choose the right tip: Match patch size with a caliber-appropriate jag or loop.

2. Solvent pass: Wet a patch with a quality bore solvent and push from breech to muzzle in a single, straight stroke (don’t reverse mid-bore).

3. Agitate (optional): For stubborn deposits, brush with a caliber-matched brush, then follow with fresh solvent patches.

4. Dry passes: Run clean, dry patches until they come out light gray to clean.

5. Protect: Finish with a lightly oiled patch to inhibit rust—avoid heavy oiling in gas systems.

Fit Tip: If a particular jag feels too tight, switch to a loop-style holder or trim a corner for a tailored fit. Bore tolerances and jag diameters vary by brand and platform.

Storage & Care

• Keep patches dry and sealed to preserve absorbency.

• Store away from open solvent or oil bottles to avoid accidental pre-saturation.

• Allow used solvent patches to air out before disposal in accordance with local guidance.
