For my .308 I mainly use it at the bush. Fiordland.
If sighting for 50 meters, it will be dead accurate between 0 and 150-200 meter (1 cm high on 75 meter, zero again on 125 meter).
For the 270 and 223 it might be better to go 100-200 zero, depending on what I expect to shoot at what range. anything above 450 yard I consider bit too far for my skill.
The range I can use (till 15.12.22 - thank you Jacinda :-( ) only has 50-200
