Just picked up my wsm 22.5 last weekend. Did the burn in and some fattys last weekend. Put 10 lb of KBB and did the minion method with it and let it burn till it was gone. This weekend looking to do some spatchcock chicken, corn and abts. But not sure how much charcoal to use and what method to burn it. Figured about about 2 hours at 325 give or take some time for the birds to be done. Any help would be appreciated.
