That is a good read, Doverham. It does explain what evidently happened. It, however, does nothing to dissuade me from using the .410 on doves and quail. I have begun to use some 1/2 oz. loads in 2 1/2" shells on doves, and have been able to tell no difference in killing ability and range. This being with full chokes, mind you.
Thanks for the link. Very interesting. BTW, I do not believe a .410 wad in itself has the energy to decapitate a dove at 23 yards. It had to be some anomaly with the shot.
