Fired up the vault again yesterday.friday night i rubbed down 2 -8# butts with yellow mustard and Jeffs naked rub then 2-4# beef shoulder roast's with willinghams origanal rub.Fired up the vault at 6am .filling the cast iron pan with a combination of kingsford hickory bricks and foil packs of hickory.( I find that using coal and propane gives a wonderfull flaver and is easy to maintain a good temp when its below freezing out.) Ohyah I also threw on a 7# ham for slicing along with the roast's. The beef was up to temp,140deg in about 3 hrs.the ham was up to temp,170.in 4hrs.both were cooled and sliced deli thin for lunch meat.the butts were taken to 170 then foiled and brought up to 200 placed in a cooler for a couple hrs and then pulled.by hand .Every thing seemed to me to cook a little faster today than ever before,butts were done in 7 hrs.I dont know why both temp gauges i used were reading 250-280 just one of those days i guess . Any way you look at everything turned out smokey and delicious. Bill
