All I use is WSM's and WSSM's and at this point I no longer see a problem with ammo availability. Cost, yes, they're more than 30-06 or standard .270 rounds, but you'd rather pay for a whole new rifle than spend a few bucks more on your ammo? I've found the .270 WSM to be an ideal deer rifle, but if you're dead-set on replacing it as your "all around," you can't beat a good 30-06.
