RE: 270 WSM
bt, I am going to be somewhat contrary to the others posts. I would recomend you get a 'stadard' cartridge. In your situation, first gun, I would recommend a 308, 270, 30-06 or 7mm Rem. Look hard for a 270 or 30-06.
I am sure the 270wsm is a fine round. If you bought one you would likely be happy. It will do anything the other rounds will do. I consider it a cartridge for someone who already has a safe full of guns, not as a first gun.
Good luck and good hunt'n
