I liked the results Mike Campbell posted on the 16 ga. forum using the Polywad insert and loading 1/8 Oz. on top of the insert rather than all shot underneath. I don't know what quarry you are pursuing, but if you drop down a shot size, you'll more than compensate number wise for the loss of an 1/8 oz. In that the shot will be closer, the smaller shot will not lose as much energy at the distance intended as opposed to using it on longer shots. Gil
