Looking at getting a new gun for moose hunting this year just wondering what everyone uses/ suggested currently shooting a savage model 111 30.06 but was considering something in a 300 short mag any suggestions?
If you want a new gun, buy a new gun. However, there isn't a single critter in North America that I'd feel under-gunned to harvest toting your Savage 30-06. The 30-06 offers a broad range of bullet weights from those suitable for varmints up to 220gr premium bullets that will drop the largest Alaska-Yukon moose and, in a pinch, handle dangerous game like grizzly and polar bear.
If you don't reload and rely solely on factory ammo, 300WM can be twice as expensive or more compared to a standard caliber like the 30-06, and offer fewer options in terms of bullet style and weight.
And keep in mind that the moose, while a big animal, really isn't that tough to kill. Put one where it counts and you have a dead moose. For most hunters, especially the occasional, every-other-year type hunter, shooting magnum calibers well is often very difficult. They find the recoil very unpleasant, along with the extra muzzle flash and noise, which can lead hunters to develop a flinch or avoid necessary range time as a result.
If you're looking for an upgrade, I'd suggest putting the cash for a new magnum toward better glass, either a better optic to top your Savage or better binos. Your moose will never tell the difference between a 30-06 and 300WM.
