RE: Ruger or Savage hunting rifle
Yup... My Savage 110 came with a general 3-9x32 Simmons scope that was okay, but not the best. The base was a solid two piece Weaver base and the rings were aluminum vertical mount (screw on top/screw on bottom) and were real crappy.
I upgraded my scope (Merry Christmas from my wife!) and I went out and got some nice heavy steel Weaver Grand Slam rings.
