Traditionally, an express double rifle is the preferredweapon choicefor hunting dangerous game.
In Africa, professional licensedhunters/guides need toback up their clients when they chase dangerous orwounded game into the bush to back them up in case of attack.Onenever knows if the animal is down & outor not.
So it's a logical choice forthat and other reasons.
I suppose if a personwere togo on aonce in a lifetime big game hunt of some kind thatmightcost thousands of dollars, then they might want to have a gun capable of a quick follow up shot so they could bring homethe bacon rather than coming back empty handed. Some large animals might require more than 1 shot to anchor it, and I'm thinking about big bears and the like. It doesn't really matter how good of a shot a person is either, it just happens to be necessary sometimes.
If someone lived in Alaskaorwayout in the bushwheresome ammosaren'treadily available,then an expressMLcould be really useful.
