I’ve read on a Boston butt recipe that when the temp reaches approx 150 to take the butt off and triple wrap in heavy foil. Approximately how long into the smoking it that. I have an almost 7 lb butt so I expect to be cooking for about 10.5 hours and I in 3 hour right now. I generally don’t keep my probes in later into smoking. I have a Pitt boss. Thanks Vicky
