Scopes of different quality have different performance.
I have a 6x 42 mm Leupold on my .257 Ackley.IMO,its perfect.
I would not put a different scope on it.(Theres always SOMEBODY!!!
)
Just to verify up close performance,in a dim room,no lights on,I picked up that rifle and sighted on a small flower pot at 20 feet.No problem,I could easily place a shot,prairie dog to deer.
It might make a difference that the scope is mounted very low,and at the right eye relief.
If I look at a target,close my eyes,bring the rifle into position on my cheek,and open my eyes,I have full field,crosshairs on target.I do not have to find anything
For me,that scope,setup the way it is,is as fast and easy as irons.
