Velocity dominant determinant of kinetic energy  recall KE  = 1/2( m * v^2)
Velocity almost to exclusion of mass is operative factor
Double mass only doubles the KE
Double velocity quadruples the KE
Range affects the velocity at which the projectile strikes body tissue
Double mass only doubles the KE
Double velocity quadruples the KE
Caliber and shape of projectile influence effect in tissues and the loss of KE. Larger the caliber the greater the loss of KE.
Structure of the projectile  influences  deformation and break-up in tissue. Projectiles which fragment result in greater loss of KE. Projectiles which deform in tissue cause greater loss of KE. High velocity projectiles more likely to break up than low velocity projectiles.
Resistance or vulnerability to stretch damage depends mostly on tissue elasticity
Elastic tissue - skeletal muscle, skin, blood vessels may be pushed aside but then rebound
Inelastic tissue - bone or liver may fracture or burst
Wound track - the longer the wound track the greater the loss of stability and the greater the deformation of the projectile with resultant increased loss of KE
The denser the tissue through which the projectile passes, the greater the retardation of the projectile and thus the greater the loss of KE

Inelastic tissue - bone or liver may fracture or burst
