Size of Pork Butt on a medium egg

You can fit two 8 pounders on there.

I've done a 16 pound brisket on my medium. You'll be fine.

I have a medium and always cook 2 butts at a time. They are generally 7.5 to 8 pounders that I stand on edge inside the egg. They will shrink and pull apart while cooking. You can also lean them together teepee style so most of the area is exposed to heat. Cook indirect with drip pan at 250 dome temp for 16+ hours until meat temp hits 195 to 200. Pull and rest for an hour minimum.

Load your lump to the top of the fire ring (above the fire box) allowing maybe 1/2 inch of space between the platesetter. Light in three places (9,12, and 3 o'clock positions) and allow egg to come to temps. Make sure the exhaust smells good before placing your meat, Skatter wood chips/chunks throughout the lump. If you don't have a remote thermometer such as Maverisk ET-73, check on temps throught the night (every 3 hours max.) to verify all is well. Good Luck!

P.S. Calibrate your dome thermometer before the cook in boiling water.

Morning DarkDreamer:

I have done as many as three butts (all 7 to 8 pounds) at one time and once did two 8+ pound brisket flats at the same time. It just takes a little "arranging" of everything. Civil Eggineer gave you some great advice for the setup. Hope all goes well with the cook (but then being on an Egg, I know it will).
