Breakthrough Clean Technologies® Square Cotton Patches — 2.5" x 2.5", 540-Pack | For .45–.54 Caliber | BT-CP-S-2-1/2-540 | BTCPS212540 | UPC 854325008155

Maximize coverage and shorten your cleaning routine with the Breakthrough Clean Technologies Square Cotton Patches in 2-1/2" x 2-1/2". Sized for .45–.54 caliber bores, these tight-weave, low-lint cotton patches deliver excellent rifling contact and solvent transfer—perfect for big-bore handguns, large-frame rifles, and traditional muzzleloaders. The value 540-piece pack keeps your bench stocked for range season, hunting trips, and regular maintenance cycles.

Why These 2.5" Patches Stand Out

• Optimized for .45–.54 caliber: Ideal for .45 ACP, .45 Colt, .454 Casull, .460 S&W, .45-70 Gov’t, .50 Beowulf®, .50 AE, and .50–.54 caliber muzzleloaders (with appropriate jag or patch loop).

• High absorbency, low lint: Premium cotton holds solvent, CLP, and oil exceptionally well while minimizing fiber shed for a clean, mirror-bright bore.

• Consistent thickness & cut: Uniform density means predictable push resistance and 360° contact pass after pass.

• Large surface area: The 2.5" square footprint wipes more fouling in fewer passes—great for oversized bores and fast field maintenance.

• Bulk value (540 pcs): A cost-effective choice for frequent shooters, clubs, guides, and armorers.

Faster, Cleaner Results for Big Bores

These larger patches are made to move fouling out efficiently in large-diameter barrels. Paired with a caliber-appropriate jag or loop, the cotton square conforms to grooves and machining marks, lifting carbon and residue while applying a smooth, even oil film to protect against rust and humidity.

Ideal Uses

• Big-bore handguns: .45 ACP, .45 Colt, .454, .460, .50 AE

• Large-frame rifles: .45-70 Gov’t and other .45+ bores

• Pistol-caliber carbines: .45 and .50-class builds

• Black powder & muzzleloaders: .50–.54 caliber round-ball and conical setups

• Post-hunt & post-match cleaning: Quick cycles at camp or the bench

How to Use (Best Practices)

1. Select the right tip: Choose a caliber-matched jag or patch loop (for muzzleloaders, use a proper jag on the ramrod).

2. Solvent pass: Saturate a patch; push in a single direction from breech to muzzle (or from muzzle with rod guide on muzzleloaders). Avoid reversing mid-bore.

3. Agitate (optional): Brush with a caliber-matched brush for heavy fouling; follow with fresh solvent patches.

4. Dry passes: Run dry patches until they emerge light gray to clean.

5. Protective film: Finish with a lightly oiled patch to inhibit corrosion.

Fit Tip: If a patch feels excessively tight on a particular jag, switch to a loop-style tip or trim a corner to tailor the fit. Bore and jag tolerances vary by brand and platform.

Storage & Care

• Store patches dry and sealed to maintain absorbency.

• Keep away from open solvent/oil bottles to avoid pre-saturation.

• Allow used solvent patches to air out before disposal; follow local guidance.
