I use a bugle as a locator call and to figure out where the bulls are located. Once I can do that, then I like to move in closer and try to cow call them in. I have found that if you bugle too much, you can actually push bulls away. It depends on the situation and time of the season but in general, bugle to locate and cow call to close.
just to hear myself bugle (just kidding on that last one....well kind of).
The other bugle I use on every setup is a challenge bugle. When trying to get a herd bull with cows to commit you need to create a threat. A challenge bugle is about the biggest slap in the face you can deliver. This call should be used when in tight otherwise the probability of the bull gathering his cows and leaving is very likely.
I really think most people would be better off not using a bugle. I hardly ever use one.
5) This one is complete opinion and I am sure many will adamently disagree. But when in close consider using a bugle, before the cow call. especially on heavily ( human ) pressured elk. I blew many gorgeous setups and it took many failed attempts to realize that opening with cow calls was killing me more often than not. Congrats on the tag and have fun!!
