    Can a colliminator be used to test the tracking of a vari power scope?

    It's pretty difficult unless the rifle and collimnator are independent, and rigidly fixed. Best results would be to "shoot the square": shoot a group, go up 8 clicks, shoot another, go right 8 clicks and shoot, then down 8 clicks and shoot, then finally left eight clicks and shoot. You should end up in the starting hole. I have a friend who will zero his gun then just go up or down an unspecified number, then right or left the same, then simply revers his actions and see if the rifle puts the bullet in the same starting spot. For tracking zero as you move up in power, just zero at the lowest, go up and fire another group, then again and again until you hit top magnification. I used to test Bushnell scopes like this, discarding the ones that demonstrated an eliptical pattern to the group placement as I raised magnification.~Muir

    Thanks Muir, I get that, I have 2 vari scopes that are dodgy and thought maybe a colliminator could be used to test
    a new scope in the shop before buying, or wasting ammo
