I started taking more moose when I learned to call..... or more importantly , use the call properly.
there was some good videos from ontario out of doors I found really helpful and that all about moose site is good too. I'll see if I can find the site or links to some of the vids.
I usually start with broadcast calls when i first enter into an area. The long nasally call starting high, and ending with a fade as the lungs empty. I'll make the first one long , 8 to 10 seconds and then wait a good 20 minutes before deciding if I wanna represent a bull or a cow..... or maybe even a calf depending on what's going on. If I make noise accidentally I usually follow it with a calf squeal or with an annoyed cow call. If I want to represent a bull I'll also have to decide how mature I want that bull sound to be depending on the maturity of the animal I'm pulling in.
anyhow, I could go on for hours on this topic , though I'm no professional caller LOL
I learned alot from that ontario out of doors moose calling series... and I've had some exciting results using my adaptations of those calls. There is also a big french guy that does calls and his broadcast calls are fantastic and very worth learning to mimick. He's got some good antler scrape tricks too
