I have a used Western Field (mossberg) model 500 with c-lect choke and vent rib. After patterning at 40 yards, it centers the pattern about 12 inches high. It is very frustrating to hit trap with. I have tried wedging a shim under the front bead with some success. But, there has got to be a better fix for this inexpensive bird gun.
