Welcome to the forum. It's probably best to spend the $12 to become a paid member and read everything.

The answer to your question will be clear with a couple hours spent reading. Basically, the list of calibers you can't make with that action would be much shorter than the ones you can use. You can make it about anything save for maybe a 50BMG or a .338 Lapua

The .473 bolt face is pretty flexible; but, you're not even limited by that.

The reason a lot of folks like the Savage is the ability to try the cartridge of the moment without a huge investment.
