i have used about every call made to hunt turkeys,but have never used a wingbone.i had one made from a wingbone from last year and have been practicing,but cannot get the consistency i should.it seems like bowhunting using a kisser button[which i do ] if i could get exactly the same place on my mouth everytime,i should be able to duplicate the previous series,but i cannot.any tips out there from someone that uses one?[&o]
