    Hi Forum,

    Can you advise on this as I just cant seam to find any reference to the correct settings are?

    In chairgun, the 'clicks/Moa' can be entered as either '1/8" MoA per click' or '1/8" per click @ 100 Yards'.

    I know its only a few clicks difference but it might explain why I am shooting high, I have mine set at '1/8" per click @ 100 Yards'.

    Which is right?

    If you are relying solely on a programme for your settings then expect to have errors.

    There is only way to do it and that's with a measuring tape and some cardboard.
    Big Nikko grn memory is 1/8th"

    It just says '1/8" 1 Click' on the turret, still not clear what its trying to advise, I know its only a few clicks at 10 & 55 Yards but it all helps!

    It's 1/8th but I'd forget Chair Gun and check on the bench at all ranges and then off the bag at all ranges. You'll save yourself a lot of time and headaches. Trust the gun, not the computer in this case :)

    I find chairgun pretty good, but you have to calibrate for your "clicks" it may say 1/8th on the scope but rarely is . There is a facility on chairgun to calibrate this. You shoot a shot at a known distance, then give your turret one complete turn ,take another shot,measure the difference and put it into the program and it does it for you.

    Concur with this, I've found Chairgun to be very accurate if you calibrate the program to your turret.
    When I first got my MRad 10-50 Sightron I just set it up my usual way by shooting at the zero range. Only then did I punch in the Chairgun data and it was pretty close, calibrating the program then made it match perfectly.
    I've also been trying istrelok lately as well and the wind clock feature in that is excellent.

    No-one loves tech more than me but your gun does do things that program can't plan for and yes it is accurate if you spend time putting everything in correctly but I found that time was better spent elsewhere if I'm honest.

    There's very little difference. 1 Moa is 1.047 inches at 100 yds. So it matters very little if you're using 1/8th of 1.047 or 1/8th of 1.000.

    1/8th of an Moa is 0.13 inches at 100 yds... and at 50yds, it's 0.065 inches, and at 25 it's 0.0325...

    1/8th of an inch is 0.125 inches at 100yds... and at 50 yds it's 0.0625 inches, and at 25 it's 0.03125...

    So in airgun ranges it makes about between 0.0635 of a mm or less difference at 50 yds. Or about the thickness of the average human hair.

    I was bored at work :D

    That 8 clicks/MOA is only a theoretical value. I have tested a Nikko MK3 in real life conditions and 144 clicks on 30 metres were 16.6 cm, i.e. one MOA is 7.57 clicks. Chairgun has a window where you can give the details above and the program will calculate your real clicks then.

    Here is my full list if somebody is interested in:
    Scope range (m) nr. of clicks elevation (cm) clicks/MOA
    Nikko Platinum 6-24x56 25 44 10,40 3,0767

    Nikko Diamond 10-50x60 30 180 19,40 8,0970
    Simmons 44 MAG 6,5-20x44 25 150 12,75 8,5556

    Simmons Prairie Master 6-24x50 25,3 72 13,20 4,0143
    Bushnell 3-9x40 4,0640

    Wow, I know its only a couple of clicks at either end ranges but might as well get it right. I spent a few hours last night just searching for the Mk3 settings & found them stating 1/8" MoA & then the others 1/8" at 100 yards,..............odd!!!!!!

    Good advise calibrating the turret based on two shots with a complete turret turn between them to get it spot on, just need to find 55 yards indoors & a gun vice, as I will never get a wind free day where I shoot!

    Thanks for all the clarification so far!

    Cheers Andras... i get your point. So really the only way if you're really worried about is to measure it.

    I'm not at the level of shooting where I should comment. BUT I think most shooters would not suggest "calibrating" a turret, or even choosing pellets, based on two shots, or using a gun vice.
    This might help. A better shooter might be along to advise.

    If you've got a gun vice, there's no reason to shot at all! It only adds another chance of mistake into the system. Simply put out a measure tape at 30 m vertically, set the scope to the zero on the tape then make two full turns with the turret, and read the distance. Then turn the same click count back to check whether it is on zero again.
