A pack of three RAM scope zeroing targets with black aiming marks. Zeroing targets have a clear aiming point and a grid, so after each group you can see exactly how far the shots are from the point of aim and work out how many clicks to turn the scope turrets. The black colour stands out against the target background and helps your eye centre the crosshair. Use them at the range when you fit a new scope, change ammunition or after a scope has taken a knock, then fire a confirmation group. Grid size and target dimensions were not stated in the supplier line.
