I have just began to try learning a wing bone. I have made a couple and have been practicing a bit and my clucks sound good but yelps are iffy at best. But I don't really know what to expect as far a sound due to never hearing someone run one well. The few you-tube videos I have watched didn't sound real turkey to me. Any body got a sound file or video of a "real deal, sure-nuff" wing bone caller so I can have something to compare to. Thanks...
