Although official turkey-type people say you shouldn't use low-temp roasting for turkeys out of concern for food-borne illnesses, I've never had any problems. I think you'll see why.
First, brine the turkey overnight (1/2 cup salt per gallon of water). If weather is warm, add ice (and adjust salt concentration accordingly); if it's cold outside (below 40 degrees), just leave bird outside in brine in covered bucket.
Preheat oven to 450 degrees. Rinse turkey very thoroughly in cold water, then pat dry.
Place on a well-oiled rack, breast-side up, inside a shallow pan. Baste generously with mix of olive oil, lemon juice, and thyme; then turn back-side up and baste again. Leaving back side up, place in oven. Add some water to pan to prevent juices from burning. After bird has been in oven about 5 minutes, TURN OVEN TEMP DOWN TO 250 DEGREES. Baste with the olive oil-lemon juice-thyme mixture after about an hour, then every 45 minutes or so (there's a lot of leeway here). Once there is sufficient pan juice for basting, use that instead of fresh basting sauce. After visible portion looks fairly brown, use several thicknesses of paper towels in each hand to turn bird over so it is breast side up. Continue cooking till turkey is done. At some point before the drumsticks and wings begin to get too well done, cover them with aluminum foil.
It is customary to roast a turkey till an instant-read thermometer reads at least 165 degrees. But this brining/slow-cook method is extremely forgiving. Because I usually debone a turkey to use the meat in various casseroles (as well as having one feast of hot roast turkey), I like to let the bird cook till it reads 190 [sic!] degrees (in thickest part of thigh). you might want to stop at 180. Experiment to see what works best for you. The brining will produce juicy meat no matter how much it's cooked. But this long, low-temp roasting till the bird is VERY cooked produces not only moist meat, but crisp skin and meat that is extremely easy to pull off the bones (and separate from tendons) using only your hands.
After removing the meat from the bones, I simmer the carcass and skin with onions, carrots, and celery to make scrumptious stock for later use. I save the pan juice in a separate container, as it has extremely dense, delicious flavor.
A tip: To freeze meat for later use, refrigerate it till you've finished making your stock from the bones. Then pour stock over the meat in your freezer containers (I use one-quart yogurt containers), cover, and freeze. Be sure to label containers with contents as well as date. The stock keeps the meat moist, avoiding freezer drying/burn.
Roasting times for whole turkeys
Preheat your oven to 160°C (325°F) and use these cooking times to prepare roast turkey that's moist, tender and delicious 12 to 16 lb Un Stuffed Turkey 3 ¼ - 3 ½ hrs 12 to 16 lb Stuffed Turkey 3 ¾ - 4 hrs Turkey is fully cooked and safe to eat when the meat thermometer reads 77°C or 170°F for an un-stuffed turkey and 82°C or 180°F for a stuffed turkey.

11-13 minutes per pound if unstuffed. A 13 lb turkey should take approximately 2 1/2 hrs
A 4.3 pound turkey should be cooked in a fryer for at least 13 minutes. The turkey should have an internal temperature of 160 degrees.
well i 17 pound turkey will cook for 8 hours if it helps
The average amount to cook a 13 pound turkey which is not stuffed is about 3 hours. This is when you use the oven to bake it.
It would take about five hours to cook a 13 pound turkey on normal setting. However if there is time it is worth cooking the turkey on a far lower setting such as gas mark 2 and doing it fr 12 hours to get a more succulent bird.
The roasting time for most meats chicken and turkey is 20mins per pound so for 13 pound it will be 13 x 20 -=260mins 260/60 =4.333hours so the ans to your question is 4hours 20mins approx.

it would cost 13% more than last year!
At 1/2 pound of turkey each; 15 x 1/2= 7.5 pounds of meat, x roughly 1.5 for bones, a 10 pounder should theoretically do fine, but 15 pounds would be better, in case you have a bunch of white-meat lovers, or something.
1 stone = 14 pounds7 stone = 98 pounds(7 stone + 13 pound) = (98 pound + 13 pound) = (98 + 13) pound = 111 pound
Generally, people smoked hams for about 40 minutes per pound. However, this varies depending on the temperature at which the ham is smoked. About 230 degrees is a good temperature for a precooked ham.
The rule of thumb for roasting an unstuffed turkey is to cook it for 15 minutes per pound at 325 degrees Fahrenheit. So for a 23 lb. turkey, you should expect it to cook for about 5 hours and 45 minutes. If it doesn't have a pop-up timer, start checking the temperature about and hour before your determined time is up and check it every 20 minutes until the temperature is 165 degrees F in the thickest areas of the thigh and breast.
