Some people ask why others sift pellets. Attached is a picture of a bolt that jammed up my auger last night. Spent an hour or so taking the pellets out and removing the bolt and putting back together. I have sifted most of my pellets this year, found one bolt while sifting, one made it into the burn pot, and then this is the third. And i still have 1.5 tons of these pellets left to burn.
