I use Nosler Partitions , 130g, in my .270 for deer and elk. This with H4831 and Federal match primers gives me sub 1 inch accuracy at 100 yds with a light load.
Your best chance of seeing Moose is to use a air charter to take you away from the roads (you may still see other hunters). Hunt a lake or river , I prefer a river just because I rather move than hunt the same area for my hunt.
I hunted the 'Bob' a lot, many years ago, so nothing on current conditions. I remember it had many steep areas as I was hiking but would open up where I could glass open areas. It had elk but I never saw a lot ,it may have been me and not the area. It has great views and is worth the hike...
