buried in information

[SlimG2]

Hello all. New to the forum and looking to be new to hunting. I've hunted birds and waterfowl before but never big game. Very much interested in starting deer hunting as well as elk. I'd mainly be looking to hunt the Washington/Idaho area initially. Been on the net and talking to friends about caliber recommendations primarily for deer with occasional elk. I'm being bombarded with info about whats the best, the favorite etc. Been looking a lot at the WSM calibers but still a long way from making any kind of choice. Not being made of money, and of course not sure how this new interest of mine will pan out, I would definitely stick with one rifle to start. I'd like to get a few viewpoints from you all out there in hunting land. To sort of narrow things down I've considered the following:

.30-06
.300 WSM
7mm Remington Mag
7mm WSM
270 WSM

I know the '06 can do it all and ammo is widely available. Are there any distinct advantages/disadvantages to the other choices I listed? As this is a lengthy enough thread, I'll refrain from talking about specific rifles except to ask any Browning A-bolt owners what they think of that particular rifle. Thanks in advance to everyone....
