Thread: Sighting in

If you are 1cm off perfect left or right at 25m, that's 4cm at 100m, and 8cm at 200m, 16cm at 300m.
Even 5mm adds up to 2cm at 100 and 4cm at 200m, 8cm at 300m etc etc. That's quite a lot and you would need to shoot perfect tiny groups with zero left or right deviation at 25m to even get close.

It really adds up.

Iv got on paper at 25m with what I thought should be a good zero many times only to find it substantially off at 100+
I guess people have different ideas of precision.
