I purchased this scope to put on a 17 HRM for shooting ground squirrels. The scope seems to be high quality for the money. I'm no sure if I would put this scope on a big game rifle due to the fact that the turrets do not lock. This scope seems like a good match for target shooting or situations where you have little chance of unintended dial movement that could cost you a chance at a trophy. All and all I think this is a great value and the squirrels don't stand a chance.
