re: Turkey Choke and Ammo

No need to over think it. Turkey hunting hasnt changed much in the last 50 years but the marketing of it has. Reg full choke and some #4's still kill birds like they always did.
Or you can join the "follow me" crowd and buy the latest choke out this year that they say is "turkey" or "super full" and then buy the $5 a shot ammo to go with it. heck might as well dip your gun a spring color phase too.
