All my rifles are sighted in that way. I don't want to mess with turrets or adjusting sights and it makes it easier for me to move between rifles.
I kept track of my coyote kills for 3 years and the vast majority were between 100-200 yards (ranged after the fact). On the .223, I'm 3" high at 150 yards so for an "average" coyote, I aim a little low, with the target sitting on top of the crosshairs. A close coyote gets the crosshairs right on on the target. I know for a verified-on-paper fact that the thick part of the post is pretty much dead-on at 300 yards. This means the crosshair itself is right on the coyote's back. Therefore a "long" coyote gets that setting. 300 yards is also about as far as I want to shoot with a .223, so the result of all this is that the crosshairs never leave the coyote but do get shifted around on the body a little bit.
I do a lot of prairie dog shooting with a .22 LR and this technique is very useful there, too.
