Well I dont mess with 7 bone chuck till it hits 1.29 with .99 being the sure fire buy some motivator. Never seen one as big as whut you got. They do good to break 3 or 4 pounds most time in this neck of the woods. Guess a person could get a 9 pounder if they standing there afore the butcher go to whacking on it. Usually wind up throwing a coupla in my big chicom made with Christian slave labor Boy Scout Dutch Oven from Academy Sports and let them cook theirselves either on or in the stove. Even though that look purty good it is beneath my standards to cook chuck roast out doors. That is house food. Best left to let the wimmen cook it. Or as in my case since I have been next to the best cook in the world I normally do it myself. Mighty purty picture.
