These square patches are sized for .38–.45 caliber handguns (revolvers and semi-autos) and .410–20 gauge shotguns. They work with standard cleaning rods and jags in that range.

Why buy a 600-piece bulk pack instead of smaller quantities?

Patches are consumables you use every cleaning session. Buying in bulk keeps you well-stocked across your shooting locations and ensures you never run short during a deep clean or post-hunt maintenance.

Do these patches work for both initial cleaning and final dry passes?
