The following are what I like, not necessarily the 'best' and most certainly probably not the favorites of others.
If I wanted and old used one
I would buy a pre 64 Model 70.
If I were buying a brand new .300 Winchester Magnum, I would get a Sako 85 Stainless Synthetic, of course I'd take one of those in any caliber.
If I was in a higher economic class I'd get a Blaser.
If I wanted a good solid hunting rifle at a good price I'd probably get a Rem 700 SPS or maybe a Weatherby Vanguard.
You really could not go wrong with any of the above choices.
