Which should I get for deer hunting... I have a .270 and I love it. I just really want to add another deer rifle for fun, and I don't want to go to a smaller caliber than the .270. I hunt from thick cover to open fields..... which one would you guys choose...30-06 or .300wsm.

Also if I added a 3rd deer rifle(after the .300wsm or '.06)--- what caliber would you choose would you choose next. (7-08, .308, 7mm wsm, .243, 25-06 or any others) Thanks.
