This data was done using a 180 grain .300 win mag. I shot his rifle through a chronograph and determined his MV was 2923, after measuring the scope height and determining his bullets BC, I played with the zero distance until I found the perfect zero range that I wanted. I was setting this up for a friend who was going elk hunting. He did take a nice big bull elk at a far distance.
I have a long range set up with a sniper scope and adjustable turrets, which is what I prefer, but you can take standard gun and reliably get out pretty far. Further than you would most likely need to shoot. We went with a 400 yard zero distance, and at that range temperature really does not effect the bullet. The idea is to pick up the standard gun and aim at the belly from 0 to 400 yards if you want, but certainly at 400 you could aim dead on. Here is the dope:
Range in yards
100 7.3
200 11.2
300 9.2
400 0.0
500 -47.2
The picture shows how close these bullets actually land, with the .400 mark being the aiming point. 100, 200, AND 300 all land within the space of an AR15 magazine. I know some will object to this method, but it seems pretty straight forward to me, and produced a nice elk. If you have a closet full of bolt guns you can zero one for more extended ranges without investing any money.
