text: Sporting use Although the .30-06 was designed as a military round, it soon caught the attention of big game hunters in the United States. This new cartridge offered a flatter trajectory and carried more energy than the popular .30-30 Winchester. The .30-06 also could be loaded with the then new spitzer designed projectiles, which also contributed to extending the cartridge's performance with respect to other .30 caliber bullets fired from lever action rifles, making it easier to put venison on the table.
  It is a very versatile round that may be loaded with bullets ranging from 110 to 220 grains, which may be effectively stabilized from 1:10" twist barrels. Thus, the cartridge may be used to hunt animals of different sizes from varmint to moose and even brown bears with adequately constructed heavy bullets. Since the cartridge may be used for taking all North American big game species it was considered an all-round by hunters and gun writers as Jack O'Connor, who hunted extensively with it.
  President Theodore Roosevelt took a .30-06 to his famous African Safari along with his son Kermit and Frederick Coerteney Selous, proving that the .30-06 could bring down game of any size. Though not optimal for dangerous game, the .30-06 is adequate for hunting African plains game.
