 This is especially true if the classic brain shot is contemplated when hunting elephant where the bullet must penetrate through the honeycombed bone structure of the frontal area of the elephant's skull.Bullets which are chosen must have sectional densities of over .300 while a sectional densities of .330 are preferred so as to provide the necessary penetration on these, the largest of the terrestrial mammals.Premium solid bullets from A-square, Barnes, Hornady, North Fork or Woodleigh weighing in the range of are all capable of holding together without much deformation and penetrating to the brain.
