Which chokes do you have already? The best method to really know what is best, is to pattern your shotgun with different ammo and chokes at the ranges you think you will be shooting. For turkey basically pick the combo with the most consistent and condensed shot pattern to give you more effective range. If you are not going to try all that plus we cannot guess what will work best in your firearm, I recommend trying anything labeled turkey shot and an Xtra full choke.
