Definately the Vanguard from this list, but I have shot most of my game with a tang safety model 77 Ruger. I retired it after 22 whitetails, 2 mulies, 2 pronghorns and a bobcat.I refused to say "other" because that's literally hundreds or thousands. Between those three, the Vanguard easily. It costs a little more, but it's still a bargain and well worth it.
For the price I'd rather have a 50's or 60's vintage commercial Mauser.
I must ask: Why a .270? It does nothing a .308 cant do.
I've decide to go with the Ruger American chambered in 30-06. Accurate, reliable, and a wide variety of ammo.
