Rifle shooting out to 400 yards +/-

[PJgunner]

I usually sight my rifles in 3" high at 100 yards, but do shoot them out to 300, 400 and 500 meters depending on whatever round I'm shooting. For example, the 7x57 and .308 usually shot to 300 meters, the .270 to 400 meters and the .300 Win. mag. to 500 meters. I shoot enough that I have a strong working idea where to hold on game out in the field. I was able to hold off on a cow elk at a laser measured 530 yards and drop her with the first shot. Roughly 3 months of practice usually twice a week with that rifle was what making that shot possible.
