Called Ruger customer service for advise. They pointed me to the Weaver #12's.
Ordered and installed the Weaver #12 bases. LGS had matching weaver medium rings so installed them and bore sighted my Vortex scope.
Went to the range on Sunday and sighted it in.
Groups about .4 inches at 100 yards...
I am having a hard time finding rings, bases etc to mount a scope on my American .17 HMR.
Any suggestions and ideas would be appreciated.
The scope is a Vortex 1" 40mm 4X12
Thanks
