I find it interesting that these are hypervelocity rounds (1400 fps) which would go through the sound barrier a long way before the target and yet they hit with consistency. I have fired a 22 revolver (4 inch barrel) at 600 meters and the hit zone was the size of a bus. This was like firing a mortar.
Here is another vid showing on target accuracy with a Marlin Model 60 semi-auto.
