I have 6 pound chuck roll that has been in my smoker for about 16 hours at about 225 grate. I have done a few of these they have always taken atleast three hours a pound and I have always taken them off around 190 internal. so it is acouple of hours earlier then my quickest results and the internal is 173. when i stick a bamboo skewer through it it offers no real resistence is it possible that it is done already even with that low of a temp?
