You must be kidding? (there's no such think as AK47 caliber).
Less jokingly, I was thinking "no .308 WIN?" The Walmarts I'm accustomed to seemed to normally carry .308 Winchester.
I *think* I've seen 25-06 too, but could be wrong about that.
My bro in law had one of those 25-06. Pretty cool.. Yup, should have said 7.62.
