i have smoked a few butts in the past. when i first started to smoke, i would go to the store and buy what they called a butt but, apparently it was a shoulder??? the first couple i did, i would smoke them forever and they wouldnt pull. i would only be able to chop them.. so, after finding out what i thought was the problem, i started to ask for the butt and was pretty successful on a couple of them. so, i go to the store on saturday and get what the label said was a 7 pound boston butt.. spice it up and i threw it on the smoker at 8 am sunday.. was on the smoker at 225-250 for over 10 hours.. temp never hit over 165 but i figured it had to be done.. so, i took it out and couldnt pull it apart with the jaws of life.. freekin pizzed me off.... so, i think i got another shoulder when i thought i was buying a butt... can someone give me an edumacation on this???? thanks!!!
