RAR, the numbers do indeed tell the tale for patterns. That is, the measured constrictions. Beyond that, there are very few factors that influence pattern performance. The problem with patterning is that patterns are highly variable. You need 10 statistically analyzed patterns to say with confidence how the gun+load performs. Considering that a Cyl at 30 yards and a Full at 40-45 yards are equivalent, it is less of an issue than is commonly thought. If you aren't willing to do 10 patterns per load+gun with the "Shotgun Insight" program, then in the words of the immortal Tony Soprano, "Fugidaboutit."
