Did some chuckies this weekend. About 4-5 lbs. each. Gave them my basic brisket rub and tossed them in the smoker. Cooked them @ 225-250 for about 8 hours - they were tender but never got pull-able but were good sliced. I did the same thing with a chuckies a few weeks ago and they fell apart. Any clues here guys and gals? Thanks in advance for your thoughts and input.
