I am using the B&B competition pellets, most of the pellets I have been using are the Weber smoke fire competition. The B&B seems to work great only have about 20lbs thru the Smokefire. The Weber Smokefire competition blend I have about 140lbs of those burned. The B&B are bigger pellets but they seem to work so far haven't done anything that is over 3 hours yet on the B&B. The Smokefire's auger is a bit small but no pellet jams yet. I have only had one pellet jam on the competition, and 140lbs is about 60 hours of cook time. With the B&B I have about 7-9 hours cook time on them so I cannot say if they will not cause issues on a longer cook. I have done 1 reverse sear cook at smoke boost, and then 600+. I have done chicken breasts at a steady 350. Tonight I am doing a Whole chicken at smoke boost for 2 hours then a step to 350, for about 30 mins, and 425 for about 30 mins. No problems yet on the B&B pellets.
