But there's another consideration. The ordinary Sierra softnose and hollowpoint hunting bullets, Hornady softpoints and Nosler Ballistic Tips, which typically shoot small groups, also deliver lightning-quick kills on deer-size game. They dump all their energy explosively, opening huge cavities in the middle of the chest rather than zipping through, trailing a narrow cavity. A controlled-expansion bullet is best if you get a quartering-away shot or must smash the point of the shoulder to land your .243 bullet in the vitals. But more often than not, you'll have the neat and humane option of a shot through a deer's forward ribs.
