This has been a very interesting thread...I dont know what I learned, if anything. It seems this discussion has been going on since Dan Lefever invented the shotgun. I remember my Dad having a fit when plastic wads first came into common usage. "Damn, If it wasnt for blown patterns and flyers, I wouldnt hit anything" As to the magical powers of the 28, I think they best remain that way. I have made shots, clean kills with the 28 that are remarkable. Why? Dunno...Still killing lots of roosters here, shooting a 10 bore this week...Re: Square loads? Lets build a square barrel, gun with square cartidges...Think of the sighting plane!
