Ok, quit making it complicated, read and follow exactly.
Don't think, don't try to understand, just follow exactly.
Take gun, remove bolt, get in some kind of reasonably solid hold (gun vice, shooting bags, whatever)
find something small like a house number, fence post top, as far away as possible (100 yds good, 50 is ok)
Look through the BARELL, center it up on your selected object and make sure the gun is as solid as possible. .
Then look through the scope. Adjustment will be opposite the what the dials say, but just turn one dial.
Start with horizontal. If the line goes the wrong way move it back the other way.
When that is on, adjust the Vertical.
Make sure the BARELL continues to be on your target by looking through it each time after you adjust a dial (if its solidly locked it should be fine but CHECK)
Soon, you will have the cross hair point at where the barrel is pointing.
Take to range, repeat the pull bolt, look through barrel, point at a target, see if the cross hairs are close.
Set up target at 25 yds. Shoot once. Note where bullet hit. Adjust PER THE DIALS NOW if needed. If it at 1 inch leave it alone.
Move to 50 yards, same thing. This time it will be off double. Shoot and adjust until is within an inch.
Move to 100 yards. Fine tune it, get it horizontal dead on, 2 inches high.
You are now sighted in for out to 250 yards.
If you want to hunt, do not think about it, anything from 25 to 250 yards you just aim mid chest behind the front leg and shoot.
Find someone who is not technical to go hunting with you though.
