steve sarich,I have done jumbo shrimp scampi a couple of times on my Large BGE so far and each time turned out great. I am usually cooking them after I have cooked steak and the temp is usually around 400 to 450 degrees dome temp. I have had great success doing them on skewers and they usually take 3 to 3 1/2 minutes per side. I like experimenting with marinades. Good luck!
