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. Key Features at a Glance Dimensions: 2-1/2" x 2-1/2" (square) Quantity: 540 patches Material: Tight-weave, 100% cotton (low lint) Caliber Range: .45–.54 (use with correct jag/loop for best fit) Model / SKU: BT-CP-S-2-1/2-540 (also listed as BTCPS212540) UPC: 854325008155 Compatibility: Works with standard cleaning rods, jags, loops, pull-through systems, and muzzleloader ramrods 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) Select the right tip: Choose a caliber-matched jag or patch loop (for muzzleloaders, use a proper jag on the ramrod). 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. Agitate (optional): Brush with a caliber-matched brush for heavy fouling; follow with fresh solvent patches. Dry passes: Run dry patches until they emerge light gray to clean. 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.
