If you hold it over your head and sway back and forth, occasionally pausing to rack it on some scrub brush,you can call one of these in pretty close.
With a few grunts ,she came in to about 25yds. That was close enough for me ,as I only had the blunts I was using for rabbits and bush chickens. She was out of season anyway. She would have kept coming but I thought better of her and her calf being that close and personal with no real trees worthy of me hiding behind .LOL.
