One of my first stands made with a hand call in 1976, I was using an 870 with a 30" full choke barrel. My hunting partner had never seen a coyote called in, and I told him they were tough as nails to put down.
We had the good sense to use camo gloves and face mask from our Duck and Goose hunting.
He sat down about 30 yards from me.
I went Waa Waa Waa on a Johnny Steward PC-1 hand call, and a coyote came bust'en around the corner and brushed the end of my shot gun that was laying in my lap. The shotgun was falling off my lap and I grabbed it and shouldered it in an ungraceful motion, almost falling off my bucket. I gave him a shot up the tail pipe as he disappeared around a greasewood with 3"#4 buck.
Within two minutes, my parner stood up and emptied his Ithaca on another, shot him to pieces. I walked over to him and he was out of breath! He thought the coyote was coming after him in his hard charge. The coyote had rolled up to within 10 feet of him.
All this took place in 3 minutes tops, two dead coyotes. If I had kept calling, we would have probably got multiples.
When you blow a call, you better be on your game.
