In small bowl, combine first 3 ingredients and ½ teaspoon Ultimate Steak Seasoning; whisk to combine. Set aside.
Prepare grill to medium heat. Sprinkle shrimp with remaining 1-1½ teaspoons Ultimate Steak Seasoning. Wrap one-half piece of bacon along the back of each shrimp and place on skewers, making sure the skewer goes through both ends of bacon.
Brush skewers with half the sauce. Place on grill. Grill, turning occasionally, until shrimp is cooked through and opaque in color, about 6-8 minutes. Brush with remaining sauce the last 2-3 minutes.
Make Ahead & Freeze: Prepare step 1 in a quart freezer bag. Prepare step 2 and place in a gallon freezer bag. Place both bags in a gallon freezer bag. Seal well, label and freeze. Thaw completely. Prepare grill to medium heat and continue with step 3.
*Note: For a mild sauce, use regular ketchup in place of the spicy ketchup.
