Oversized 3" Square Patches for 12–16 Gauge Shotguns
These Dewey patches are purpose-built for 12 gauge and 16 gauge bores, giving you the right balance of snug fit and smooth travel when paired with the correct jag or patch holder. deweyrods.com+1
Ideal for:
12 gauge shotguns (field, tactical, or competition)
16 gauge shotguns used for upland, clay sports, or general hunting
Smoothbore barrels that benefit from maximum patch contact
The 3" x 3" square design provides plenty of surface area, allowing the patch to wrap around the jag and press firmly against the bore, lifting fouling rather than just smearing it along. Palmetto State Armory
100% Cotton Flannel for Superior Absorption
Each patch is made from cotton flannel, the preferred material for serious gun cleaning thanks to its softness and absorbency. deweyrods.com+1
Benefits of Dewey’s cotton flannel patches:
Excellent solvent absorption – holds your bore cleaner or oil where it’s needed
Soft, non-abrasive texture – gentle on barrel steel while still grabbing fouling
Even contact with the bore – pulls residue, powder, and fouling out efficiently
This makes the Dewey BPS-3 3" square patches a strong choice for both routine post-range wipe-downs and deeper seasonal cleanings.
Built to Attack Fouling and Protect Accuracy
Clean barrels are essential for consistent patterns and long-term barrel life. Dewey designed these patches to help your shotgun stay free of powder residue and other fouling that can build up and affect performance over time. GrabAGun+1
With the right solvent and technique, these patches help:
Remove carbon and powder residue from repeated shooting
Carry out loosened fouling instead of leaving it in the bore
Make it easier to inspect the barrel and confirm it’s clean
Regular use of quality patches like these supports more consistent shot-to-shot performance, especially important for clay shooters and hunters who depend on predictable patterns.
250-Count Value Bag – Stock Up Once, Clean for Months
Each bag of Dewey 3" Square Patches contains 250 patches, giving you a generous supply for multiple shotguns and many cleaning sessions. deweyrods.com+2Palmetto State Armory+2
Why the 250-pack makes sense:
Ideal for high-volume shooters and frequent range users
Great for multi-gun households with several 12 or 16 gauge shotguns
Cost-effective versus constantly buying small packs of generic patches
Whether you’re prepping before hunting season, cleaning after sporting clays, or maintaining a dedicated home-defense shotgun, this bulk bag keeps you well-stocked.
Compatible with Most Standard Shotgun Cleaning Setups
The BPS-3 patches are designed to work seamlessly with popular shotgun cleaning rods, jags, and patch holders that match 12–16 gauge dimensions. Palmetto State Armory
Typical use cases:
Pushed through the bore on a shotgun jag or patch loop
Used behind a bronze brush as a follow-up to scrubbing
Employed as final dry or lightly oiled patches to finish the job
Because they’re square and generously sized, you can also fold or cut them for lighter-duty tasks if you want a slightly looser fit in certain setups.
