So would a couple of hours at a decent patterning board at measured yardages. I have gotten back into it lately after acquiring more guns than I owned at the time I was really spending a lot of time doing it (c. 1970s-80s). I can tell you, the results are really eye-opening and there are some real surprises. For instance, as Dean notes, plastic shells with poly shot cups tend to show tighter patterns, but the modern soft-wadded loads (felt-wad RST, Eley, etc.) consistently show better patterns with more even distribution at given ranges.
