Well, after shooting some Hornady knockoff flight control OO Buck (Patterned worse than any other buck I have shot), and regular remington buckshot (Patterened okay). I shot WInchester Supreme XX 2.75" OO 12 pellet buck. This stuff does VERY WELL! It is probably the best patterning OO out of my Benelli M4. So I disected a round out of curiosity. I found 12 shiny copper plated OO pellets surrounded by white polyeurethane or whatnot granuals and 2 synthetic/foam-like pads under them, but not shot cup. I cut open another to be sure. Nope, no shot cup at all. What gives? THey pattern great! Is this due to no shot cup blowing through the pattern? What is the deal here, did I get a wierd lot or does the Supreme XX just not have a shot cup?
