Years ago I probaly would have said The remington.I personally have mostly Model 70 action (pre-64 or the newer "classic" model) which is basicly the same as a Pre-64 but I think some better upgrades.As far as caliber again I personally don't like any short,super short ,short ultra,or any of these new short magnums.I just don't see much future in them unless you reload.Also I feel you actually lose with these unless you reload.If you are set on a .270 I would reccomend the Model 70 in the old favorite .270 win.You can get .270 win. ammo anywhere .It is aboutas available as 30-06 ammo plus if you roll your own you can use 30-06 brass in a pinch because it is one of several calibers that are based on the 30-06 cartridge.JMHO
