  • Mathematical scope adjustment

    HI all,
    Usually when I zero a scope I basically chase chase my shot strings around via windage and elevation until I get consistent groups of less than 10mm at 10M,
    Recently I used an app on my phone that calculates the adjustment by where you place your shots on the target on the app,
    I was pleasantly surprised, did a 5 round group and put my shot placement onto the app and it gave me my corrections in clicks up/down - left/right,
    App is called sight set,
    Would recommend it for anyone trying to zero their airgun,

    Thanks CS. Will try and find it.
    Believe none of what you hear and only half of what you see.

        I think the OP was refering to the maths needed to make adjustments at 10m when the scope adjustments are calibrated for 100m eg; 1 click = 1/2 inch at 100 yds.

        That's a perfect method if your rifle is a laser and 1 holer. Ideally I suggest fireing a group of 3-5 and centre in the middle of your group. And your rifle set up so you don't have to hold it in position. If your rifle is shooting a 2" group then you just zeroed your rifle on the possible edge.

        Great post none the less john23 it explains a simple method very clearly. Even when sound is off (-;

        Edit. I meant to quote johns video instead I made a general reply
