This is from another post, but I figured I wrote the novel, so I'd pass it along some of our Elk tactics. These are some calling/chasing tactics we have picked up over the years:
1) Don't over Bugle and learn to listen the Elk. You can tell when a Bull just wants you to answer him so he knows what direction to push his Cows.. AWAY FROM YOU! Learn to chase those. Become a "lost cow" trying to catch up to the herd or join him. You might be surprised when he holds a bit or comes back to get you for his herd. (This really works earlier in the year when they are herding cows)
2) Getting that I'll just hold up at 100 yards and you come to me bull! Won't go into my details here. ELKNUTS tactice above for those that hold up is AWESOME. We use a variation of this, but it's basically the same thing. A cow trying to leave the herd for the real elk's bugle. One thing I would note is if you are hunting alone, you might be able to sneak into the bull using cow calls to mask your movement, acting like the cow coming to the bull. Be careful... he will be looking for that cow coming and zeroing in on the sound, making you more at risk to be seen.
3) Change up your bugle and sounds. Play with em! I don't think you can produce that bad of a bugle to scare them off. Unless you start squeeling like a dead rabbit!
4) WATCH and just don't stare at one bull... anyone who has chased Elk alot knows of the infamous "Satellite Bull". Some bugle leery bulls without cows will come in silent trying to steal a cow or two. This is very common with rag bulls or even spikes. Big, roaming bulls will do it too.
5) Become a herd of Elk. Walking around won't spook Elk (before you've actually spotted them or close, etc.), especially if you and your hunting partners mix in calling and talking like a bunch of Elk. We really like the Calf/Cow combo of sounding like a herd of Cows and Calves. They seem to like company and will bunch up in bigger herds. Bulls know this.. they will come. More COWS equals...
6) Wind.. always remember the darn wind! I'm all for "Scent-Lok" this and "Scent-Blocker" this, but I personally feel unless you are a millionare and buy EVERYTHING scent free and everyone that hunts with you does too, they only "help", barely. I absolutely hate these ads that say "Forget the Wind... just Hunt". Well, hunting is all you do.. shooting and killing you won't! I take the Real Estate approach... the 3 more important things bowhunting.. Wind.. Wind.. Wind.
Anyway, hope this all helps and good luck hunting!!
