Abstract

A method of making a projectile that tumbles upon impact. The projectile has a leading portion, a leading portion trailing end, and a leading portion side which forms a leading portion acute angle with the leading portion trailing end. A tip extends from the leading portion and has a tip trailing end and a tip side. The tip side forms a tip acute angle with the tip trailing end.

Claims (28)
