The Pedersoli Rocky Mountain Hawken in .54 caliber uses the same 31.5-inch octagonal barrel platform as the .50 caliber but in a heavy bore suited for large game hunting. The .54 caliber delivers more energy at close range with patched round balls than .50 caliber, making it the traditional choice for elk and moose hunters.
