Mosin Nagant 300 and 600 yard zeroing questions.

[Aragorn243]

I may be missing something here but if your rifle is zeroed at 100 yards, you loosen and adjust your scope elevation ring at 100 yards and lock it down. Then all you have to do is crank it to either 300 yards or 600 yards and it should be dead on without having to guess anything. The scope should have settings from 100-800 yards.
