My top picks for rifles in 270 would depend on the look and feel you like, if you want a slim ultramodern design the Tikka T3X gets the nod, I LOVE that rifle, but their wood is kinna bland so if you want a wood stock in an ultramodern consider the Browning X-Bolt. If you like traditional sporter weight rifles the Weatherby Vanguard is a REALLY nice gun even in synthetic, and yes those Winchester 70s are worth every penny especially if you want a nice hardwood stock, mine is a 308 and it shoots right at MOA with factory 150gr Core-lokts and about half that with my SST handloads. In regards to the Ruger 77 I have one of those too, while it is the least accurate rifle I own it still gives acceptable accuracy for hunting (1.5ish MOA) and I love the weight and balance of that rifle, that said their synthetic stocks leave much to be desired.
