JMR40,
I disagree strongly that "there isn't enough difference" between the .270 and .30-06 to justify owning both. If somebody doesn't own both, their Campfire comparisons lack the EMF (Essential Minutiae Factor) that lengthens elk-cartridge threads, some of the longest not just on the Campfire but Planet Cyberspace.
I suggest you have one of your hunting buddies give you a .270 Winchester cartridge, or if he's really cheap, sell you one. Then you can claim to "own a .270" and thus help keep these threads alive.
