Shooting Winchester HV (black hulls) 1.75oz #6's, my best targets were110 pellets in a 10" circle at 30 yards,80 pellets in a 10" circle at 40 yards, and 30 pellets in a 10" circle at 50 yards.
I do not like a pattern that has less than 100 evenly spaced pellets in a 10" circle at any given distance so to me it was an honest 30 yard gun.
