The reading didn't seem too dusty just had some junk in it and didn't seem to last as long. The last bag of stove I used I dug out i kid you not a soft ball size rock of course after I tried burning all the goodness out of it! Lol... the miners choice that i got from TC sat seems to be burning good a close 2nd to the blaschak maybe even the same. No clinkers yet, fine, grey ash, and still lots of blues in the am when I get up.
Maybe I just got a bunch of bags of reading that were just crappy..
