It is a good second call to use in an area, when you return for a second or third time. It would work good if the coyotes have heard the same type of rabbit squealing, for a while. I took one old male that came in from down wind, he didn't know I was 20' above him in a boulder pile. I was using my open reed Bill Austin male call as a deer bleating. He came in under cover until the last 30-40yds, he was looking in the right area, smelling the wind, but missed my scent and I shot when he was at 35-40yds, he almost went down spun and grabbed the ground for all he was worth. I sent another 55 Nosler at him but it hit a sapling, he died on his feet just under the sapling. That was the only coyote I ever shot with a 55 Nosler in the shoulder that didn't collapse instantly.
He did everything right, but so did I! T.20
