Question for the veterans, I’m brand new to smoking. I have a OJ Bronco drum smoker, I did a long 10 hour chuck roast using Kingsford blue and white bag and held 250 the entire cook. Neatly stacked coals around perimeter working to center. Lighting a couple from one side so it could work across during cook.had great success. Tried repeating method using B&B competition oak&hickory. Could not seem to keep temps under 280-295. And that is even with intake completely closed and also pinching stack to 50%. Ambient temp very similar. Is the B&B just too hot? With Kingsford intake at 1/2 stak open 100%. Thanks for feedback
