Here's the current players one my team:
.22
.270
.30-30
.308
.32 spl
.35 rem
7mm mag
.300 win mag
.50 front stuffer (As Beaverjack would call it!!)

I've hunted deer with all of 'em ('cept the .22) and prefer the .270. For elk I only use the .300 win mag. One doesn't always need the magnum power, but if that big bull is only going to give me a quartering shot, I don't want my bullet skipping off a shoulder blade. Just my personal preference. I may add a .338 to the roster and that would be on the chance that I get to Alaska to hunt one day.
