What should pellets in the AMNPS burn down too to be considered a proper burn? I just used mine in my 30" MES for the first time cooking chicken drumsticks and they turned to black charcoal, but stayed in pellet form. No white ash except where I started it with the heat gun. Smoke seemed good, nice TBS. Traegar hickory pellets. It burned a little less than half a row in 45 minutes.
