Well I brined a pork loin and shoulder overnight, dried with paper towels, rubbed them down, and smoking them now. The loins were pulled at 3 hours and an IT of 145. The shoulder is at the 4 hour mark and is at an IT of 136. Should I be worried about the 40 to 140 in 4 rule? I have a Masterbuilt Gas Smokehouse and the temp has been around 225 (210-245). My thermometer was placed in the loin after 1 hour and then pulled and put in the shoulder when they were done. I have the Maverick ET-732.
