Like others have posted, either a 7 RM or .300 WM will easily kill a moose, as will a .30-06 and a long list of other cartridges.


In the mid 80s, I took one of my friends moose hunting in SW Montana. Frist thing opening morning, one shot from his 7 RM dropped (at that time) the 4th largest B&C bull moose ever shot in Montana.


Also in the 80s, I was lucky enough to draw two Montana moose tags. One of my bulls had a 50" spread, the other 40". Each was killed with a single 180 grain Nosler Partition bullet from my .30 Gibbs, which is an improved .30-06 with approximately .300 Winchester velocities.


If I ever go on another moose hunt, I'll probably use my .300 Weatherby.
