Did an 8 hour cook of a relatively small (5.5lbs) Boston Butt yesterday. Bad Byron's Butt Rub and Jack Daniels wood chips. Total cook time was eight hours at 275 dome temp. One hour resting in a cooler. Served up with toasted buns and coleslaw. Food went too fast but I did get a pic when it hit 190 degrees. Took abount one hour to get the temp to stay at 275. It kept fluctuating 10-20 degrees, but when I got it "locked in", it was fire and forget the whole cook. Gotta love it.
