Getting back on topic:
A shotgun that will do it all, i.e. waterfowl, turkey, coyote, dove, quail, grouse, chukar, etc. is going to be a compromise. There is no subsitute for a quick handling well fitted scattergun for flushing birds. Pass shooting birds or coyote, turkey, etc. generally does not require a quick mount so a heavier weapon can actually smooth out abberations of your form. In either case, a shotgun that fits YOU is paramount to hitting what you look at.
