Nice to see the results. We had a very different experience, just about opposite outcomes. Did you have any ash cakes at all?
No, didn't have any. These might have gotten beat up in transport or something. Pellets that come from the west end of Canada had less fines and dust than these.
Blaksesley used to have them at one time. I got some a while back. Mills try to be as consistent as possible, But fiber can very enough to cause variations. I've had several instances where I had opposite results as others. Kind of put it in the chit happen category(batch variance)!!
