When Is Your Shot Patterning Correct?

The pattern of pellets within a 30-inch circle should be of a proper, even density to ensure a clean kill. The pattern should contain a sufficient percentage of the load, which should be at least 55% to 60%.

Continue this process, trying different choke and load combinations, until you get an even pattern density with a sufficient percentage of the load within a 30-inch circle while shooting from the distance that you expect to be from your quarry.
