Hmmm... need more info... ... what gun are you planning to use... gauge, barrel length, intended shell, (2 3/4, 3 or 3 1/2), and prefered shot size. This would help with answer your inquiry more specifically.

If it's a general, "what do you use for turkey", question you're asking, then disregard the fist sentence. You're apt to get a massive numbers of answers in all calibers.
