I use a Rod Benson grunt call, never leave home without it. I rarely blind call, I mostly use it when I see a buck and he's not coming my way. I use it to turn them and call them in for a shot on better look. Sometimes they come trotting, sometimes they come very slow, sometimes they stop and look then keep walking, sometimes they act as if they heard nothing. Like a box of chocolates , never know what you're gonna get.
