Yes. . . well, no. . . wait . . . well, maybe?
Look my history with calling is checkered. Yes, I have called in deer with blind calling. I have also called in the two biggest bucks of my life. However, do I feel blind calling is a good idea? Generally no.
Here are the two times I have called in the biggest deer of my life:
Taking The Big One in 2003: The Savage Spoke. . .
Taking the next Big One in 2007: The Savage Spoke Again. . .
These were. . . semi-blind instances. In 2003, I had a deer grunting at me, but I did not know it was a deer. In 2007, I was grunting at one small group of immature bucks and they took off like I'd lit their tails on fire. The reason was that The Big One was lurking out there, and they thought I was him.
I think these instances are good examples of how blind calling gives mixed results. You may be calling blind and The Big One may be out there and be tired and sore from the last fight and not want to give it another go. You may be calling blind and The Not-Quite-The-Big One may hear you and decide you are too big for him and scoot.
When I do blind call, I do a very non-committal non-descript type of calling. I voice it between a doe and a buck. I keep it a simple contact grunt/bleat. I want to sound like the deer equivalent of Pat.
I figure everyone wanted to know if Pat was a guy or a girl, right? They were curious.
