Smoker was and has been at 230 all day with some normal variations and 7 hours into my smoke my brisket was 150 and the internal temp was dropping. The chuckie was at 148 but it took all of 7 and a half hours to get there. First time I have ever smoked beef and I'm not real happy about this. I have sinced foiled the brisket and chuckie and put them in my oven at 350. The really weird thing was the brisket temp was at 150 for a hour and a half so I re-probed and the temp went to 152 and started coming down from there. Then the grill dropped down to 150 and I had to get a new chimney lit fast it was no longer then 20 minutes later and the grill temp was back up to 230 but the brisket was 138?????????? The current temp of the brisket is 154 and climbing so please smoke gods tell me wtf is going on!
