I have blind called with rattling and had decent success with it in Idaho.I have blind called with a can while hunting and have never had a response,although I have close friends that have had very positive experiences.With grunting,I can count on a couple of fingers the times I have done it blindly.I have grunted in bucks that I have seen from a distance or heard grunting but couldn't see.
If I jump deer while still hunting or on my way in to a stand,I immediately get on my grunt tube with a couple of soft grunt's.(I want the oh it's only Larry the little buck response).In Idaho where the ratio's are much better balanced I have called back countless deer that I have jumped,doe's and small bucks.Big bucks are not particularly curious in those type of situations unless you hit it just right and they are frothing with fury.
I know of some of the big buck killers who will not call to a target buck under any circumstances because of possibly educating them and having them use the area differently.I am going to grunt to a buck to try to draw them closer,I may do it very softly and escalate up a little but I am going to try.
