If the Mauser is properly zeroed, in good working order and I’m 600 meters away, no problem. I’m no Carlos Hathcock, but I should be good for that.
My old man made it through two tours in VN and did some amazing things with a bolt rifle there. I’m not as good as he is, but I’ll do. And he was easily able to perform the feat you have just described.
600 meters? That would be tough. You’d only get about two shots before they start to return fire.
Granted the sights say a thousand meters(I think, it might be 2000), but that’s meant to be done in large volleys shooting at very large targets or massed troops.
In other words, it never happens.
