I don't particularly see the appeal of a rimfire scope on an HMR as the main advantage is the closer parallax setting. I don't sight my HMR in at 50 or 60 yards so that doesn't seem an advantage to me.
My current Ruger 77-17 is wearing a proven Weaver V10. I feel like 10x works well for small varmints out to 200 yards which is about how far I generally feel comfortable with the HMR. My V10 also has a slightly smaller objective (36mm) which compliments the smaller action.
