I am smoking an 7# turkey breast this afternoon. On the smoker at noon with a set temp of 240F. Now at 3:30pm, and the breast has stalled at 154F for the past 30 minutes! No worries, don't need it to hit 165F until 4:30-5:00. I wanted to share this for folks that want to smoke a turkey breast to be aware that it does stall, so allow at least 4-4.30 hours for this sized breast.
