For most of my informal range work, I staple up a full size combat silhouette target, backwards, then using a variety of paper plates with 1, 2 ,3 ,5 etc inch holes cut in them as templates, use black spray paint to apply aiming points, the number and size dependent on what I m shooting, and how far. With an accurate scope sighted rifle, I might have 40 aiming dots on the paper. Along with the use of a spotting scope, it saves a lot of trips down range during load testing.
