I asked him that, he said it's "My dream girl, who will remain nameless."

When I first saw it, I thought it was a picture from CNN and it was a policewoman from India or something. I think a .308 would be impractical, more gun than neccessary. A smaller bullet would be better.
I would say a .25-06 or a 7mm-08. If all you're going to do is deer and lope hunt, than a 25-06.It can also be used as a varmit rifle. If you want to hunt elk later, use a 7mm-08.
I think a 7mmWSM would be way too expensive. Since it's still a wildcat cartridge and isn't produced that much. 25-06
