Welcome to the Forum. The honest answer to your question is that it is all up to you. You can smoke and cook the turkey 100% in the Bradley. If time is constrained, smoking in the Bradley and then transferring to the house oven may make more sense as certainly your house oven can get hotter than the Bradley. Whichever way you choose, be sure the vent on the top of your smoker is 100% open as the turkey will release a lot of moisture that you want to get out of your smoker as quickly as possible. Moisture that is trapped in the tower will hold the temp down.
Either way, you will be in for a treat. Let us know how it goes.
