I usually start with a heavy half a chimney. When I am going to do a big cook I start with a little more that 3/4.
As far as the amount of charcoal... it seems to vary based on the size of your fire ring. Mine is about 17 or 18 inches in diameter. I have gotten to where I put a large coffee can with both ends cut out in the center of the ring. Then I fill up the ring around the coffee can with briqs. I would say I put about 14 or 15 pounds in. After the chimney briqs are ashed over I dump them in the coffee can and then pull the coffee can out. Then I put my chunks of wood in for flavor and let it rock.
