When selecting cotton patches to maintain your firearm, remember that the best performance will be achieved by matching the caliber/gauge and size of the patches to the bore diameter. Patches that are too large can be difficult to pass through the bore and can even jam up. Patches that are too small may not provide enough contact with the bore to effectively clean or lubricate your firearm. Remember, unless the last patch comes out clean and white, you haven't effectively cleaned or lubricated your barrel yet!
