Both WY Moose hunts we did were during the rut. It was a blast. Had a homemade cow call, if we saw a couple black spots in the brush, and could not see what they were, we'd call and the cow seemed to pop out first out to look, followed by the Bull. Not sure if that is typical or we had a magic call, or maybe it was an inadvertent lost calf call... Have been part of only 3 Moose hunts, so not very experienced with Moose, Ak and two in WY, the ole coffee can call worked when we used it. In 26 the year we hunted, it opened 10/1 as I recall, it was an opening day harvest and the rut was on. Go and have fun, and a little one is big! They are excellent eating, we especially love Moose roast.
