I am currently smoking at 6 pound flat brisket and it's been in the electric smoker for 15 hours and the internal temp is stuck on 169 degrees. The smoker temp is set at 225 degrees. I wrapped it around 150 degrees.
As this point I'd say take it out, chop it up, and use it for chili. I've had pieces of meat that never got tender. It happens. Makes GREAT chili though!
are you going by the temp gauge on the smoker? or using a digital thermometer in the cook chamber? the issue might be its not actually 225 might be 200 or 190 or lower
