PARALLAX adjustment is a VERY IMPORTANT TOPIC when shooting at long distances, which is given too LITTLE attention. And if it is not adjusted, then with the slightest change in the position of the head (after each shot) the reticle will also shift, and where the hell will you hit (although, perhaps, you will hit it exactly there, even though you shot in the head)…
1. Diopter adjustment
After choosing the magnification at which shooting will be conducted, it is worth starting the adjustment – Reticle Clarity.
It is important to remember that good eyesight (young eyes) quickly adjust the clarity of the reticle themselves, so before making sure of the correct setting, you need to LOOK AT SOMETHING LIGHTER, and then make sure that the reticle does not “float”.
Then close your eye for a few seconds and look into the optics again using a light background, if the setting is correct – the reticle will be clear.
2. The next step is to restore PARALLAX.
PARALLAX is the displacement of the aiming reticle relative to the aiming point due to a change in the position of the shooter’s eye relative to the eyepiece of the optics.
Using the parallax adjustment drum, it is necessary to achieve the clearest possible picture – the Reticle and the TARGET should be in focus.
3. CHECK It is necessary to tie the crosshairs of the optics to any convenient aiming point, preventing the weapon from moving, look into the optics and nod your head to CHECK whether the POINT OF VIEW IS NOT DISPLACED in relation to the target.
If a parallax error is detected, adjust the drum until the problem is eliminated.
A satisfactory result of correctly adjusting the optics should be as follows:
– CLEAR sighting reticle.
– The TARGET is clearly visible.
– The reticle DOES NOT DISPLACE on the target due to a slight change in the angle of the shooter’s eye in relation to the optic eyepiece.
IT IS IMPORTANT TO REMEMBER THAT PARALLAX MUST BE ADJUSTED EVERY TIME THE MULTIPLICITY IS CHANGED.
P. S. Case study: Distance 723 meters – Remington 700 – Discovery optics – multiplicity 12. The cadet was found to have a spread of 2 meters vertically and horizontally. After checking, it turned out that the optics were defective and the parallax was not rebuilt at multiplicity above 6. After twisting the multiplicity by 6 and rebuilding – they took and confirmed 700 and 800.
Good luck and happy hunting, Gentlemen!
