My last two were done in 9 but I wrapped. Put these on at 7 and at 9:30 they are 130 shooting for 200 but need them done by 6-7 tonight. Running 250-275
I hate wrapping butts bc I love that crispy bark mixed in, but I would in this case if I were you. It will be close otherwise and some rest time before you pull them isnt a bad thing. Foil at 145 which is the stall temp. I would definitely get the smoker up to the 275 you are saying so get more bark before you foil.
I foil just for the help it gives through the stall and the time that it saves. I like the bark that I get but not the really black crusty stuff. So, I guess the foil doesn't bother me. Butts is the only thing that I foil. I'm still experimenting with a lot of different meats and cuts. Maybe my whole method will change several times, but it's interesting to do.
I did two 9lb boneless butts in 8 hours a couple weeks ago. 300F for 6 hours until IT was 178. Then wrapped each with 1 cup apple cider for 2 more hours at 350F to an IT of 203F. Crispy bark plus tender juicy insides. Smoking well past the stall then wrapping gives a great bark.
