I am going to go for it and guess you have a Boston butt on ?
Seeing this makes me want a grill like yours, an auto feed with flavor, what brand is it Mike ?
It's a Pit Boss. Bought it at Wal Mart. I put a brisket on. It's a small one about 10#. I separated the flat and the point and I will make some burnt ends out of the point. They should look like this.
