These days it isfashionable to speak about niches in the marketplace. There are automotiveniches, and housing niches, and clothing niches, and (for all I know) quicheniches. There are niches in rifle cartridges as well, and one of the mostinteresting is the trio of very powerful cartridges that are meant for thebiggest North American game and much of what you hunt in Africa. Far morepotent than any 7mm or .30-caliber magnum, they are also much longer-ranged andmilder kicking than really big rounds like the .416 and the .458. Allessentially .338 caliber, they offer a unique combination of truly significantwallop, long-range capability, and manageable (by many people but noteverybody) recoil.
