Congrats on a great bull.
Way to follow your instincts.
Its pretty cool when you see one that far off and he responds to a call.
I called one from almost as far once bivy camping up in a basin. That bull ran in to 60 yards...I was still in my sleeping bag.
My first bull I put in for a crap tag in Montana for a few reasons:
1. I had a dall sheep hunt booked
2. I didn't have much leave and wanted to hunt closer to where I lived
3. It was any moose
4. It had really bad odds.
The season didn't open until Nov. 15 and went until Dec. 15 really a season to shoot moose off haystacks in the bighole. Found one good bull, too bad he'd already shed an antler. The other thing it was a real pain to get around to much moose country with the snow.
Ended up with this one, at least it wasn't a cow and did have both antlers:
Second Shiras tag was 2015 in Wyoming, found this bull:
