It would be if it had American origins, had picked up an American/English caliber designation somewhere along the way, or been championed by the American shooting press. Fine round that punches above its weight. Europeans have been using it in Africa as a “do it (almost) all” caliber since it came on the scene in the early 20th century.

Only have the one due to shoulder issues - 358 WM. That rifle/cartridge combination has been instant death on whatever I shot. For fun I tried to hit at 500 yards. Scared the steel but never hit it. Had to hold it in the bottom of the scope and pray.
