Is this the Sabati (sp?) wad? If so, below is 24 grams #9, 16 gr 700-X, WW 209, AA hull out of a NID-4E 32" left barrel of full choke at 20 yards. You might want to consider this a benchmark for effective spreaders. Remember also that the crossover point of effective pattern diameter between open and tight chokes in in the 25-30 yard range, depending on how open and how tight. Can the idea of full choke making 40 yard rifle shots - doesn't happen.
