I have a cherry K98 (8mm Mauser) from 1936 that has a tang sight out to 2000 meters I can’t ever imagine a shot at that setting where I live unless I set up on a bridge overpass on and interstate.
Pray that does not become necessary.
Fond of my Swedish 6.55x55s ........
That range was used for massed area volley fire. It doesn’t mean that it was intended to engage a man-sized target at that range. More likely, the shooter was ‘aiming’ at a formation of moving troops.
Troops used to do a lot of things we don’t really do any more; not because we can’t, but because we are not present with those type of targets any more.
