RE: 7MM's in Alaska
160-175gr bullets work very well for moose, carabou, and bears. I don't see why 175gr bullet in the 7mm isn't enough but a 180 in 30/06 is? They are ballisticly identical. I know a couple people who hunt moose with thier 7mm and 162gr hornady and 160 accubond come pretty highly recomended. The 175gr bullets work fine for most bears, even the large coastal bears will die readily enough with a premium bullet thru the vitals.
