I really enjoyed reading this thread. I personally spot-and-stalk for mule deer and call/ambush for elk, but I have yet to kill either with a bow. Many, many close calls, though--I think I'm doing it right; I just need to do everything slightly better. For rabbits and grouse, I use the tried and true "wander around likely looking country and shoot 'em when I see 'em" tactic.
I've never tried using a predator call for cervids, but on a couple occasions I have seen a doe mulie take in after a coyote and (literally) kick its butt. So I could sure see how it would work. I've never tried deer calling, either. Mulies aren't as vocal as white tails, but they do talk to each other a bit. After last Saturday, after once again running out of light belly crawling through the sagebrush toward five nice bucks that were completely unapproachable anyway, I'm considering giving it a try.
