RE: How long for a Cow moose Call?
For locating or drawing a bull I too use a 3 set call. Duration is 4-10 secs, however when locating I will use 2 longs(8-10) and 1 short (4-6). If I know moose are close I do short(4), med(6) and short(4). If I have a visual or know he is close I will stick to placing a 6-8sec single call to where I want the moose to come/go, his response or reaction dictates what I do from their(more cow calls, bull grunts &/or raking). I end all my cow call's with a short soft grunt..oowah(sound). The best way I can describe the sound of my cow calls is RRRRRrrrrrrrraaaaah..oowah(grunt). To get a mental picture of what a cow moose sounds like think of a beef cow call, but instead of the M sound you put R sound and pitch drop into the end aaah sound (nasally). The technique described by Corey is what will produce a nasal sound and how I do it as well. However some find pinching the nose when calling helps to get a bit of nasal into the call as well.
