There are lots of good rifles out there. And like Cam said everyone has an opinion. Go out and shoulder as many rifles as you can at all of the local retailers. Find one that fits you, that shoulders nicely. Once you have the make and model then look for the calibre.
Again, everyone will have an opinion. Of the 7 guys in our deer camp, there are no two rifles alike, and everyone is using a different calibre. 30-30, 270, 243, 30-06, 308, 300WM, 7-08.
So if you are looking for one calibre to do both deer and moose... 308 and 30-06 are both good ones. Most of the hype on any calibre is designed to sell more rifles. Find out what is popular calibre in the area, measure that against the calibre you think you want, and then check the supply of factory ammo at your local gun store and CT. If you have someone who reloads, talk with them, get their input and get them to teach you how to reload.
Component availability will be an issue in the not too distant future, so popularity will be a factor.
What ever you spend on the rifle, spend 3/4 of the amount on glass. So if you buy a 700 dollar rifle, spend 400-500 on a scope.
Then go to the range and practice, practice, practice.
Thats my two cents for what its worth.
Good luck its a great sport!
