Shooting paper targets can be very difficult when compared to aiming at a 3D target, pencil, a clump of weeds, or a dry cow pie!. With each of these targets, it is easier to pick an aiming point because their is no bullseye. With a paper target, you see a yellow, blue, or white bullseye and aim at that circle, not a small point. I do much better stump shooting at unknown distances than shooting at paper targets at known distances for that reason. As stated above, aim small, miss small.
