In fact, since momentum (mass * velocity) is conserved as well as
energy, it doesn't matter at all how much resistance the target has.
If the bullet hits the target and no chunks go flying off, then all
of the momentum of the bullet is transfered into the target.  So the
velocity of the target changes by a set amount

delta v of target = velocity of bullet * mass of bullet / (mass of
target + mass of bullet)

No matter how much energy is dissipated as internal damage, noise,
heat, etc.

Conservation of energy is not very important in determining how much
the target will move; conservation of momentum, on what part of the
target the collision takes place, and biological factors (muscles
going limp, etc.) are much more important.
