I'm doing a 3 1/4 lb. Boston butt, and its I just passed the 7 hour mark, and yet the current temp is only 165. As far as the temp of my egg, its been perfectly steady at 260 the entire time (230 at the grate). I know the general rule is 2 hours a lb. for butts, but perhaps that applies to larger butts, in which they typically are on for 15 hours or more. Do smaller butts generally take longer than 2 hours a lb. since they simply aren't on as long? Any thoughts would be appreciated.
