Good info from all those above^.
Here's what I do:
Bore sight at 100 +/- yards to get it close (look down the bore then look up through the scope and adjust accordingly)
Shoot one (1) shot at 25 and make adjustment to zero. Remember that it takes 4 clicks,with a 1/4 MOA adjustment, to move the POI 1/4 inch at 25 yards = it takes 16 clicks to move it an inch at 25 yards so don't be bashful.
Shoot one (1) shot 100 yards and adjust accordingly to hit where you want. (for elk I like 3" high if you're not using an external turret. that way you're good to do to 300 yards with that cartridge)
Shoot a 3 shot group to verify that the center of your group is where you want it to be. Make a small adjustment if needed and maybe shoot another 3 shot group.
The above process will be complicated if your rifle sprays bullets like I pee nowadays.
No joke, you can sight in a rifle with just 2 or 3 shots! Literally, I've done it a hundred+ times for me and other over the decades.
