The sizing logic is the same as with any patch, but the consequences shift: on a large-diameter barrel an undersized patch is even less effective, because the gap between patch and rifling grows with bore diameter. You end up making passes that accomplish very little and reading a clean patch as a clean barrel.\u003c\/p\u003e\u003cp\u003eSquare patches are the sensible default over round ones. They fold onto a jag more predictably and are less likely to roll off their own edge partway down the barrel — which is how patches get stranded in a bore.\u003c\/p\u003e\u003cp\u003eBuying in hundreds is not overbuying. A genuinely fouled barrel will consume ten to twenty patches in a single session between the wet passes, the brushing, and the dry passes at the end, and a used patch put back into the bore is just returning the fouling you removed.\u003c\/p\u003e\u003cp\u003eMatch the size to your calibre using Bore Tech's sizing chart rather than by eye. If you shoot more than one bore diameter it is worth keeping both sizes on the bench — they cost very little compared with the barrel you are protecting.\u003c\/p\u003e","brand":"Bore Tech","offers":[{"title":"Default Title","offer_id":43019640930375,"sku":"BTPT-134-S100","price":6.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8250\/4519\/files\/4327_source_1736215378__11074.jpg?v=1785358691","url":"https:\/\/extremestore.us\/products\/cleaning-patches-square-1-3-4-in-100-count","provider":"The Extreme Store","version":"1.0","type":"link"}
