YesI know this should be a basic task. I have never really had a lot of scopes on any of my firearms. The ones I did have were already sighted in. If you are shooting , lets say high and to the right. Do you turn the adjustment down and to the left? Sorry for the dumb question.
shooting low requires UP adjustments.
then you must have the (offset) scope base on backwards somehow.
If bases are perfectly drilled to centerline and rings are perfectly milled to centerline and exactly the same height, then scope centerline is perfectly parallel with bore centerline. scope adjustments being at midpoint means your pretty close to dead on zero. your only adjustment is vertical to overcome gravitys effect on bullet flight time, which will be minimal adjustment at a 100 yd zero.Pretty much what the first reply to the OP was.
I would have to say that I don't agree with you. Cyrano posted basically how to center the crosshairs. I don't see how you lose half of the adjustment capabilities... You just start in the middle instead of the bottom. Which might require a lot of clicks to get you on center.
Back in my days of dealing with the m16a2... you did exactly that.. center the sights and then count the clicks for your personal settings... You could pick up any m16a2 and "reset" the sights and add your personal adjustment and you are dead on without firing a shot.
I call it chasing the bullet.One simple way (to me anyway), is to set your gun up on a steady rest, ie: sandbags, shooters rest, etc. and move everything around so your crosshairs are on target without any input from you. Carefully squeeze off one shot. Set the gun up exactly the same as before. Now use your adjustments to bring the crosshairs to bear on the bullet hole you just made and you should be extremely close, but you may have to make a few minor adjustments. I usually do this at 25 yds and then recheck at my intended zero range (usually 200 yds).
...I also print my own "sight-in" targets. They have a med gray bull on a white background, and includes a 1/4" grid printed on the target.The single shot method described above works well for me. My son and I adjust for each other.
I put one of my rifles on a rest and carefully line up on the target center. Then I squeeze off one round.
I reset back to my original aim point on the rest and hold the rifle steady.
I then have my son adjust the turrets until the crosshairs match the impact point.
That gets me pretty close, then we spot for each other and see how the groups go. You can then make fine adjustments yourself by looking at the grid on the target and turning the turrets the appropriate number of clicks to compensate, but usually the one shot method gets you really close.
Yes, the adjustments move the point of impact.The scope's windage and elevation knobs have arrows marked "right" and "up," turn the knob in the direction marked "right" to move the point of impact right. Do the same thing with the elevation. And if you want to move the point of impact down, turn the knob in the opposite direction.
