Hi i recently downloaded some targets on line which print off A4 size, these have inch black lines going across and up and a bullseye in the middle, i found these very useful when zeroing, and also seeing just where the mildots are for different ranges, if you can keep the gun still. it has really helped me hit the HFT targets at my club, providing of course its not too windy, if the wind is taking the pellet you can see on this target how many mildots too allow at different wind speeds. portisaacboy
