And to answer your question. They are generally very accurate. My Stag 3L will put .75 MOA groups out there when I'm doing things right. 1 MOA is the norm. I had the same concern at 1st... Concern is gone after firing.
Now, hitting that coyote at 200+ yards while he's in a dead run in a 20 mph wind... Tough, but it isn't the rifles fault ;-)
