This is the first new model in years, chambered for the .17 Mach II - good on Whittaker and Ruger for making these available (if only for a limited run).
Was just at the range with it again this morning... shooting up the last few rounds of my old Remington ammo, and then a few magazines full of CCIs 17gr VNT load.
No issues, and very good accuracy. Not as much 'fun' as my 10/22 conversion in .17, but fun enough.
Picked mine up at Whittaker's yesterday. I have #220 of the 300 gun lot. I was told they still have several in stock. Mounted a scope last night, and hope to get some range time this week.
