I do Brisket far and between. Got a 7lbs and fired the WSM up too 225. Slapped it in and probe read 45 degrees. 45min later it read 100. Wa-What. Changed out probe unit and it read 110. Checked both temp gauges on the WSM and they were both spot on. I have never had a Brisket rise that fast. It's been on for little over an hour and it's at 132. Is this normal? In a little bit of a panic. Any insight would help?
