sighting question

[drache]

Got a rifle sighted in at 50 yards. Now how many inches should be raised to go from there to 100 yards?

.308 150gr.

Just need a rough estimate.

2.5 high at 100yds is 1.15 high at 50 yds. and 225 yard zero.

so get it hitting 2.5 high at 100 , which should be 5 clicks up if it is dead on at 50.

this would be the optimal setting for deer sized game

In my experience, (this is with 180 gr), my .308's zero'd at 50 hit the paper 1 to 1 1/2" high (depending on which rifle) at 100 yds.
