Checking Crosshair to Turret Squarness
Do they make a tool or does anyone have a good method of checking how true the crosshairs are with the turrets? I know there are tools and methods of checking the squareness to the rifle but how about to the turrets themselves? Obvioulsy this would be for exposed target style turrets. I would like to get under 1° accuracly if possible.
Thanks in advance for any help.
