Found a beeman chart .

I notice that PA does list pellets by head diameter on the left side of the site when you select a pellet caliber . But after what I saw today with accuracy with my Disco {and I have been wrong before } at 35 yards and the WC grouping well and the RN not . When it should be the other way around . And the difference being in the skirt diameter being .004 larger with the WC I think that the skirt diameter plays a big part in accuracy . The contact area of most of these pellet heads are so narrow that I would think that if the skirt is not tight at take off that the pellet would have a good chance of cocking to a side while it is starting to move .
