The 7-30 is a little on the light side for moose. I'd go with the .358 with the Nosler Partition. They are big, big animals are are not responsive to lightweight, high velocity bullets. It's better to go with a heavier, larger diameter bullet that can punch through thick hide and bones to reach the vitals. A .358 rifle using a Nosler Partition fills that need well.

The most terrifying sound in nature is not the roar of a charging lion, nor the whistle of a descending bomb; rather it is a click when you expect a bang. - Peter Capstick
