Warren Page, Field & Stream's late, great shooting editor, had a test for consistency that he called "the one-shot group." He would take a rifle to the range, fire a single shot, and save the target. He would repeat the process for the next 11 months. At the end of the year, he had a target with a dozen holes in it-12 one-shot groups. A good rifle would turn in a single ragged cluster, and that is what you want.
