jcardella, welcome to the SMF , glad to have you here and hope you enjoy our little piece of the "Net".
First , please stop by the Roll Call and properly introduce yourself to the rest of the bunch.
Now to the Turkey. We cook to an internal temperature , there
are rules of thumb to get close to the finish time, however they are just that...rules of thumb.
Cook your Bird to 165° to 170° in the thickest part of the Breast , with brineing , you will have a nice , juicy Turkey. Also make sure the juice in the Thighs runs clear when cut and the joints aren't reddish.With a 'brined' Bird , 170° is better.
If you don't already have a good thermometer(probe type) , it would be a good idea. Tracking your temps. through the cook helps in assuring a well cooked Bird.
You can get a decent Probe Therm. at either Wally World , Lowe's , HD , Bed Bath and Beyond, or Target. If you haven't used one , you'll be amazed at the ease of use, just don't touch any bones.Make sure your new therm. is reading correctly by calibrating it in boiling water(212° @ sea level , or the cold test- @ 32°).As a note:we highly recommend using the probe ; it gives a real time look at the temps.
Cooking at 350° seems a little high IMHO, most of us do them at 275° to 300° , but a fast cook is good as long as you get the "done" temps. in the deep meat -Thighs and Breast .
Be sure to re-wash the Turkey after brineing and pat it dry , then add your rub and (as I like to do,take some Butter mixed with some of my rub , and rub it all under the skin to "help" crisp it some) and get a bunch of flavor to the white meat.
I hope this helps in your cooking adventure. Be safe and happy , if you have more questions, feel free to ask , we take pride in helping our members.
Have fun and smoke happy
