i have a mossberg 500......i have tried #4 shot, #5 shot ...i got awesome patterns with the #5's @35 yds and closer........winchester supreme,double x magnum turkley loads, 3'', 2 oz. loads.....it's never let me down......
i personally use the factory full choke, the turkey choke at close range has too tight of a pattern , i believe for me , it's better that they spread out a lil....
