i usually use 5 or 6 shot 3 1/2 inch 12 gauge mags. Winchester has a great turkey load. If you do not have a shotgun capable of 3 1/2 (which can shoot accurately up to 50 yds) then get the 3inch mags. They will put them down quickly. If you make a good head shot they will flop around for a few minutes. Its similar to a chicken running around with its head cut off... its ok. they are not suffering
I was born and raised in NE but never knew that wild turkey thrived there. I guess I was too fixated on slaying pheasant.
I have however, fired a hot 3 1/2 turkey load (unbeknownst to me at the time). Be sure you're prepared!
Are the turkey located throughout the state? What is the best region to hunt them? I have already made plans to go here in KY this fall but I would love to set something up in NE for maybe next spring.
