My big Game gun is a Model 70, Super Grade in .416 Rem. I had the original 24" pipe whacked to 21" with good set of express sights installed, and Talley quick release bases and rings, holding a 1X5X30MM Kahles. The express sights are regulated for 400 Grain Barnes Bonze solids and 400 Grain Sledghammers, the scope is set for a 300 grain Barnes X load to shoot 2" high at 100yds. I don't shoot the gun off of the bench often, but I can tell you this. The difference in 100 grains of metal is like the difference between a 243 and a 300 mag! When I practice with this gun I alternate between shooting sticks, offhand and bracing against a tree with the 400 gr. loads out to 100yds, to simulate dangerous game situations...I do the same with the lighter loads, at farther distances. but throw some prone position rounds out to 300yds...

I use the same method basically that William describes in his post of sighting in for center of group, as I'm a hunter, not a target shooter. I had a PH in Botswana one time that "made" me shoot from a rest at 100 yards to check zero...My rifle was almost three inches high, and an inch right...put three that would fit inside a quarter....he was digging around for something to change my scope, when I asked him to let me shoot offhand, shot four about as quick as I could, two cut the bullseye, 1 was an inch low and left, one was an inch high and right. He put his screwdriver back in the truck..
