Ray - Sorry I didn't see you post. Skinner has it right and here is a Butt "Bone in Shoulder" we cooked Sunday. Started out at 7:30am.
At 12:30 the meat was at 165 and came got trayed, foiled and sauced to go back in til it reached 200 at 2:30. Out to sit for 1/2 hour, pulled and enjoyed.
Cooking on this thing is a lot of fun
