Mine was 7 pounds trimmed, no bone. Got it on the smoker at 8am, kept the smoker at 250 for the first 5 1/2 hours when it reached 150F, then wrapped and into the oven for the last 2.5 hours (which took it to 4pm) when it reached 203F then it rested until about 4:45 or 5:00 when we pulled it.
So 8 hours total cooking time to get to 203F.
I'm using the maverick 73. It's wireless range is a little short, but it's worked great for me, and I can do an antenna mode on it to boost the range if needed.
