RE: Good long-range deer calibers.
The tikka t-3 is fairly light and is available in 7mmremmag.All tikkas must shoot 1" groups before being sold so the odds are very good that they will be accurate.Be aware though that reguardless of the cartridge,lighter rifles do provide more recoil.I fired a ruger ultralight in 270win that produced just as much felt recoil as a standard weight 300winmag.
