Abstract
A projectile for a centerfire cartridge achieves maximum energy transfer with limited target penetration. A hollow point lead bullet is provided with an aluminum jacket which allows the cartridge containing the projectile to feed reliably in auto-loading pistols and yet does not restrict normal expansion of the bullet upon impact with the target. The jacket extends into the nose recess of the bullet and covers the peripheral portion of the bullet base, whereby the jacket is securely fastened to the bullet and separation subsequent to impact is prevented. A method of fabricating the projectile is also disclosed.
