Over the last 20 yrs, I have got into a routine of sighting my rifles at 1 inch high at 100yds for stalking. I also routinely check the impact of two shots on a target at 100yds. The first shot being a cold clean bore shot and the second being a follow up shot. If both shots are within an inch of my aiming point, I don't adjust anything. Prior to this, the rifles I was given to shoot were similarly sighted.
Given the opportunity, it's useful to check where your shots will fall at up to the maximum range that you intend to shoot. I shoot on a range that has a 230 yd firing point so I have a fair idea what I need to do to hit the bull at that range, although I wouldn't normally shoot at deer as far away as that.
