A good article . While most Americans such as myself have little or zero experience shooting double rifles many of us ,however have grown up using SXS double shotguns extensively so it might surprise you how fast we can be with a Double . I love to use double guns for upland where 2 quick shots are most important .Only rarely do you need a third as game birds are then long gone.I can see in Afrika the need for 2 really quick shots can mean life or death
