Colorado - I use mostly Denim. It is avaiable from Yard Goods (sewing supply) stores in thicknesss from about .008" to .035" in thickness and mostly everything in between.
: One must take calipers or michrometer to the store when buying it. Make sure it is 100% cotton. I find denim the best as it's locked stitch seems to hold more lube and is stronger than the compercial ticking I tried.
: We've been shooting denim for 35 years and more and find it still is the best.
: It maintains it's integrity up to over 15,000 psi and 2,300fps, as proven in the small bores up to .45 calibre. This is relevent as pressure is what destroys the patch, not velocity. However in the small bores, you get both higher pressure and much higher veocities as well. Your 12 probably never gets over about 7,500 to 8,000 psi, even if used with 200gr. charges. This, of course, is provinding you aren't cutting the patch at the muzzle when loading.
