I'm fairly certain they are burned since the hole is pretty well centered where the back side of the ball would rest. The pillow ticking does seem much dryer than the pre-lubed patches from Cabela's.
I know that a lot of BP powder shooters use the same method (water & Ballistol) to make dry lubed patches; and they swear by it. I have seen their comments about improved accuracy from this technique; but I have never seen anyone mention the patches turning into donuts. I am pretty sure mykeal uses the same type patches. Perhaps, he can shed some light.
