Nice. My shiras hunt was probably the most fun hunt I've ever been on, it was not easy. I ended up putting 21 days in the field for it and I finally shot a good one. I didn't feel like if I saw a good moose there was a 100 percent guarantee that I would see him again so the ones that I passed on were difficult. When I finally found the one I wanted I didn't hesitate. Hope you can find that bull again if you don't find a bigger one.
Are they responding to the calling? I found that grunting was pretty effective but I could never get them interested in the cow call, though I was hunting a few weeks later in the year than it is right now. Can't wait to see some pics and a video. It is certainly a lot easier to make P&Y than B&C, however, I really feel like the wolves have the moose acting very un-mooselike. They are a lot more wary than they used to be so stalking into bow range is probably a challenge.
I still haven't had mine professionally scored but I scored him over B&C by an inch or so.
