I have the .270 Cal with that scope.
I can sight in a target at 4-500 yards pretty good. But you are not going to count points at that range with any 9x40.

You are welcome to check it out prior to your purchase if you want.. Just drop me a PM.
Overall the scope is nice picks up light well and is very clear. but it is a 9 power.. My next scope will most likely be a Nikon but will go up to at least 16 power
