Getting Back to Your Question, Servo.....
I have a Win 70, Black Shadow (it wasn't called Stealth 4 years ago when I bought it, so may be slight differences) in .30-06. Gets good groups with factory ammo, including some sub-2 inch groups at 200 yards with my hunting ammo (180 grain Barnes XLC).
Have used it for three Alaska hunts in the past 4 years, have shot caribou at ranges from 150 to 275 yards with no problem. I'm gonna buy another model 70 in .338 Win Mag for bear hunting.
If you're a hunter, it's a great field gun - 3 positon safety, controlled round feed, reliable, etc. You'll love it!
