Super America is Kimber, super grade is Winchester. I wouldn’t be without a .30-06, owned them in Winchester super grade, Kimber Montana, Colt light rifle, tikka 695, Steyr MIII, REM 700, REM 742, Browning A-Bolt medallion and gold medallion, valmet 412, and probably more I can’t remember.

I’d go Kimber Montana before Winchester super grade.
And a 2.5-8 only if it was Vari-X and well proven.
Mine wears an SHV 3-10.
