So, I'm attempting my first ever pork butt smoke today, and it's taking much longer than I had anticipated. Started a butt just under 5lbs at 11:30am today. Took until 7pm to hit 165* internal temp (smoker temp varied between 225-250), at which point I foiled it and put it in a 250* oven. It's now 9:15pm, and the temp is only reading 182*. It was reading at 194* for a short while, then started creeping downward. I moved the probe at that point, and now it's reading 182*. How long should it take to get a smallish butt up to ~205*? I'm almost at 10 hours, which is considerably longer that the 1.5hrs/lb estimate (7-7.5 hrs). Any thoughts?
