I did 17lbs of Pork Butt today, actually started last night and loaded my 18.5 WSM slap full of lump and it ran for a little over 7 hours at 225-250 before temp started to drop and I checked and 90% of the lump was gone so I loaded it up again for the 2nd half of cook. Took 14 hours to hit 195 internal. What's the longest you have cooked on a load of lump, what temp and what were you cooking? Thanks!
 
Thats about right for average lump, 8-10hrs. Good lump like Wicked Good, Ozark Oak or Humphreys can go much longer.

Here is some O.O. after 10hrs:

This was a 2 butt (9lbs each) with water in the pan as well!
 
If you just pour the lump in, 10 hours at 250 is very good. If you sort the pieces and carefully pack the ring, it will last 14-16 hours.
Edit: I get these results w/Royal Oak in the summer.
 
WoW! 14-16 hours on one load. I had 2 butts in it with a full pan of water. I usually use my BGE for butts and super long cooks but thought I would use my WSM this time. I use Mali's lump and it says "Gourmet Lump Charcoal" for what that is worth. I have tried Cowboy, BGE, and Royal Oak and I seem to get the longest burn times with the Mali's. That is basically all I can find in my area. I can go 18 hours no problem in the BGE with Mali's. I have to ad that it was quite windy here during the cook with gust up to 23 MPH my weather station recorded with a constant with wind 5-10MPH. I am sure that helped it burn faster. Like it had a blower in the vents. I need to make a wind break protection like is shown in top photo.
 
Yep, on a 18", really full ring, good lump, no water in the pan and no impact from wind/weather and I can get 16 hours. Anything that needs more that that will likely see the oven. I'm not big on reloading - I strive for one long burn.
 
In this cook i got 22 hours out of the 22,5 WSM till it started to drop in temp. Thats the longest ive gotten out of a single load. The load whas about 9 kilos of briketts.

Edit.

Sorry! I didnt read the whole question. Now i see its about lump not briketts.
 
Eric your 22 hour cook with lump or briquettes is a Super feat to accomplish! Thanks for sharing.
 
Rob -

I use briquettes for extra long cooks. Seems to pack tighter in the ring and gives longer burn times. Even after 14-16 hrs. I still have a handful of briquettes left over. A friend of mine uses nothing but Royal Oak lump in his 22" WSM and packs the ring very tightly. He usually gets around 12 hrs. out of one ring of lump by packing the ring tightly.

You are probably right about the wind making it burn faster. For a wind break, I use a folding plastic table on one side and the back, and half a sheet of plywood propped up with a couple of concrete blocks on the windward side. Works great at home on the patio, but isn't very portable.
