I buy flannelette by the yard of meter at the sewing store. It takes only one patch on the jab to clean the gun and 4 or 5 to dry it, then one to oil. The 4 or 5 + oiling patch are reusable as the drying patches are only wet, not dirty.
The dirty patch used for cleaning, once rinsed out, is only stained and is reusable next time as well. After about 3 uses for cleaning, it is discarded as it's getting a bit ragged.
This type of cleaning, of course, is when the barrel is removed from the gun and the breech of the barrel is immersed in water. The water is sucked into the bore and blasted out using a patch on a jag - in and out, in and out about 20 strokes cleans the bore of ALL fouling. Then the bore is dried, WD40 blasted, then patched out, wiped down, reassembled and stored muzzle down until next time.
It takes about 10 to 15 minutes to clean a muzzleloader, is all. It takes longer to clean ANY of my modern guns, other than my Sharps. The Sharps is a wet patch, dried with 2 then oiled - done. All of those are reusable as well. Flannelette - best cleaning material there is - doubled - as long as the JAG is filed or sized (electric drill in a vise makes a quickie lathe for reducing jags in size) to hold a double layer of it. The doubled flannelette will get down into the deepest of grooves.
