Jim: the gobbler bones will make a good turkey call, one they will respond to well. I have made wingbones from hen and a 100 or so gobbler bones, the hen does have a higher pitch. We have had good success with gobbler boned calls in the woods. The key is in the mouthpeice, i do a lot of hand sanding on it to thin it up and shape the mouth peice to get the desired sound, another major factor is to leave the mouthpeice as long as possible. Trkyhtr is correct on the air due to the larger diameter of the bone opening, However the amount of air needed can be controlled to a degree by the depth of the call between the lips and the amount of pressure applied. I made a hen call some uears back, even though i carry at least 3 wingbones on every hunt the hen call never saw the woods this past season, it certainly doesn't have to be made of hen bones to call that ole gobbler in. Have fun and good luck, if you have trouble shoot me a pm
