I did some patterning the other day using Win's 3" 4 shot turkey load and Mbergs UltiFull .695 choke vs Kicks GT .685.Both at 40yds did so well I jumped to 50.Still excellent patterns.Still both chokes neck and neck.I decided to hold off before going to 60yds until I get some plywood/catalogs or whatever to start checking penetration.With both chokes doing so well that's all that matters at this point.
