Well I patterned the Ic .665 against the Pg .670 today and the patterns were almost identical out of my gun the IC averaged about 4 to 10 pellets more per pattern and averaged in the 285 in the 10 both were very good patterns at 40 yards. I guess I will stay with the IC .665 because it did shoot to point of aim at 40 and the Pg was 6 inches high.
