I have coooked many butts in the smoker and they all turn out delicious...however I can never pull them. Whenever I pull them, I the meat doesn't come off and I always end up just chopping them. I typically cook in a my offset smoker at 225-250 for 1.5hour per pound (give or take depending on the beer i've drank). I even bought the bear claws....but they don't work. Am I not cooking them long enough? Help...i've got a BBQ on the 4th of July for 50 people!!!! Thanks!!
