Yes, I have.
We blew some distress call's while woodchuck hunting a couple times........just to see.
They did stand quickly, then about 3 seconds later shoot down the hole for good.........not to be seen again all morning or evening if that was the case.
Don't use it......unless you just want to shoot one and are ready for a quick shot.
I think the coyote have been chomping them in the summer because they sure new the sound of a critter being mauled and down the hole they go.
